This a very clean well maintained coupe. The M6 has been affectionately called the "Bavarian Ferrari" and most BMW enthusiasts have one listed on their dream list. I looked far and wide to find this beauty but now after 6 years and a family tragedy I am forced to find her a new home. This car is as much fun to drive as it is to look at. Gas mileage is in the low and high 20s for city and highway. It has been modified with a Dinian performance chip, a smaller thick (very comfortable) custom German steering wheel (replacing the large “bus driver” stock wheel), a stainless steel exhaust (nice throaty note), a Bavarian Auto catalytic converter and sleek euro front turn signals (replacing the protruding US import versions…which are included). Only Mobil One synthetic oil has been used. The car is also listed in the International BMW “M” Registry. The leather interior is in excellent condition and has been conditioned regularly. The dash is protected from UV damage by a custom templeted cover that we lay on it when not under cover. The cover is included as are manuals, a first aid kit and safety gear. I originally had 2 complete sets of wheels. A set of TRX 415s and a set of 17” M5 style with Pirellis, photos of both are included. Unfortunately a thief left me with 2 of each. The tires on the TRXs are like new, however the 17” tires need to be replaced. I will leave it up to the new owner to decide which way to go. Most M6 owners have replaced their metric wheels but purists will run on nothing else. I am sure the sale of 2 would pay for any replacement. I have included the following tech and production information to explain what all the hoopla is about: HistoryWhat makes the M6535CSi/M6 unique? The M635CSi and M6 are the BMW Motorsport-developed versions of the E24 6 Series coupe and are powered by twin-cam, 24-valve inline-six-cylinder engines known as the M88 or S38, which were both derived from those used in the M1 sports car. They also feature a revised chassis and several unique cosmetic items.What’s the difference between the M635CSi and M6? All examples of the BMW Motorsport-developed E24 6 Series coupes are officially designated as the M635CSi. However, in both North America and Japan, they were known and badged as the "M6", both to simplify the name and to bring it in line with the other M models, specifically the M3 and M5.When was the M635CSi/M6 first introduced? The M635CSi was introduced at the 1983 Frankfurt Motor Show.Where was the M635CSi/M6 built? Like all 6 Series, the M635CSi/M6 was built on the normal Dingolfing assembly line, with body shells shipped from the Karmann works in Osnabruck.Production DataHow many versions of the M635CSi/M6 were developed? BMW Motorsport developed five different versions of the M635CSi/M6: Two non-catalyst models for the European market (left-hand drive and right-hand drive), plus three distinct catalyst versions for Europe, North America and Japan (all left-hand drive).How many of each version were produced? Model 5531 (ECE/LHD without catalyst): 3,283 produced from 2/84 through 12/88 Model 5532 (ECE/RHD without catalyst): 524 produced from 09/84 through 02/89 Model 5511 (ECE/LHD with catalyst): 117 produced from 11/86 through 12/88 Model 5514 (NA/LHD with catalyst): 1,767 produced from 11/86 through 09/88 Model 5519 (JAP/LHD with catalyst): 164 produced from 11/86 through 03/88DrivetrainWhat makes the M88/S38 engine unique? The M88 and S38 engines are evolutions of the 24-valve inline-six developed for the mid-engine M1 supercar. Like that engine, both the M88 and S38 share a displacement of 3,453cc (via a bore of 93.4mm and a stroke of 84mm), and both have a four-valve crossflow cylinder head (with 37mm inlet valves and 32mm exhaust valves) designed for better breathing at high rpm. However, for their application in the M635CSi/M6, the M88 and S38 have unique pistons and connecting rods, as well as more advanced Bosch Motronic fuel injection/engine management. To save costs, both engines utilize the standard steel M30 crankshaft and wet-sump lubrication system. Many other smaller items, such as the ignition system, are shared with the regular 6 Series as well.How do the M88 and S38 engines differ? The M88 is the non-catalyst version of the S38 engine. With a 10.5:1 compression ratio, 264-degree camshafts and a single-row timing chain, it is identical to the one found in European-spec E28 M5 sedans. Power is rated at 286 hp (DIN) at 6,500 rpm with 251 lb/ft of torque at 4,500 rpm. The M88 can be identified by the BMW Roundel and only the words “M Power" on its valve cover. The S38 is the “clean” version of the M88 motor, introduced to comply with North American emissions regulations but also offered as an option for European-market M635CSi beginning late in 1986. It utilizes a duplex (double-row) timing chain and 248-degree camshafts, and features a lower 9.8:1 compression designed to work with catalytic converters. This reduced the horsepower to 256 hp (SAE) or 260 hp (DIN) at 6,500 rpm and torque to 243 lb/ft at 4,500 rpm. The S38 can be identified by the words "BMW M Power" on its valve cover.What kind of gearbox does the M635CSi/M6 have? All M635CSi/M6s have the Getrag 280/5 five-speed manual gearbox. Gear ratios are as follows: 3.51 (1), 2.08 (2), 1.35 (3), 1.00 (4), .81 (5). A 3.73:1 final drive is fitted to all but the North American M6, which uses a 3.91:1 rear end. All have limited slip differentials with a maximum locking of 25 percent.ChassisHow is the suspension of the M635CSi and M6 different from that of the standard 6 Series? Both the M635CSi and M6 utilize a MacPherson strut/semi-trailing arm suspension design that is common to all E24 6 Series. However, it has been tuned by BMW Motorsport and features a number of unique components. The suspension of the M635CSi is more dramatically altered than that of the North American M6 and includes the following changes: -Specific front and rear springs (also fitted to E28 M5s produced before 10/86) that are stiffer (by 15 percent) and result in a reduced ride-height (by 0.4 inches) -Increased steering caster -Specially-tuned Bilstein shocks (also fitted to E28 M5s produced before 10/86) -25mm front anti-roll bar (up from 19mm) -16mm rear anti-roll bar The North American-spec M6 shares its springs with the standard North American-spec E24 635CSi (as well as the European-spec E28 M535i) and therefore does not benefit from a reduction in ride-height. However, it does include unique shocks and a larger (compared to the standard North American 635CSi) 21mm front anti-roll bar that is shared with the early European-spec E28 M5 and North American-spec E28 535i/535is. The rear suspension is largely identical to that the North American-spec E28 M5, complete with automatic load-leveling rear shocks. Unlike the E28 M5, however, it retinas the smaller 16mm anti-roll bar from the M635CSi.How is the steering of the M635CSi/M6 different from that of the standard 6 Series? Both the M635CSi and M6 are equipped with a recirculating ball steering system with an overall ratio of 15.7:1. Most were fitted with regular ZF engine-speed-sensitive power assist. However, European-spec M635s were offered with an optional (and quite rare) ZF Servotronic (vehicle-speed-sensitive) system beginning with 5/88 production.What size brakes does the M635CSi/M6 have? The M635CSi/M6 has enlarged vented front rotors that measure 11.8-inches (300mm) in diameter. These utilize four-piston calipers. The solid rear rotors, measuring 11.2-inches (284mm) in diameter, are the same as those found on the 635CSi. ABS is standard.What are the factory wheel and tire sizes for the M635CSi/M6? There were two available wheel and tire sizes for the M635CSi. In most European markets, the standard alloy wheel was the same metric-sized version shared with both the regular E24 635CSi and E28 M5. Made of forged alloy, these measure 390mm x 165mm or 15.4-in. x 6.5-in. and carry 220/55VR390 Michelin TRX tires. However, the majority of cars were equipped with larger cross-spoke alloys measuring 415mm x 195mm (16.3-in. x 7.7-in.) wrapped in 240/45VR415 Michelin TRX tires. Early versions of this wheel were made of a three-piece construction. However, due to concerns about their integrity, BMW switched to a similar two-piece cross-spoke design beginning in late 1986. These later wheels were standard equipment on all North American-spec M6s.

As explained to me by the previous owner when I purchased the car, the original owner had a problem at the Ohio DMV with the title when he was renewing his registration. This resulted in the title being issued without a correction but with a mileage discrepancy. I had no reason to doubt him..he was an avid concourse enthusiast and keep the car and everything about it meticulous...he won a number of "best in show" awards. When I bought the car in 2006 it had 86,905, not 96,905...error on my part in filling out the registration paperwork...never got around to correcting it because I never ever planned to sell it. I drove to car to BMWCCA events and nice days and did not use it as a daily driver.When my wife passed away in 2010 I got rid of just about everything and needed to get away for a while. I transferred the car to my daughter who, "allegedly" as a result of some bad advise, registered it with a higher mileage in order to save some money on personal property tax.I know this is a long answer but the best I can do.I just went out to the car and checked the odometer....something I should have done before I listed it...and the odometer reads 92,103.I have had a number of higher mileage 635csi cars and you can tell just by looking at the car that it is sub 100K. Original paint, break in sticker on windshield and even has the original custom M pinstriping the first owner had painted at the dealer.Feel free to come over and see the M6...you will not be disappointed.
