The 1980s gave us some pretty cool sport coupes–cars worthy of chauffeuring around the era’s Wall Street wolves, “Miami Vice” villains and off-duty F1 stars. In addition to the usual suspects from Porsche, Mercedes-Benz and even Chevrolet, BMW offered that market the M6.

The M6 isn’t nervous like its smaller sibling, the track-tuned M3. While the M6 also has a successful motorsports heritage, on the road it’s a relaxed GT with that big twin-cam, inline-six providing turbine-smooth power.

Outward visibility is abundant. The front seats are supportive. The rears are tiny, we concede, but are still present. And you could reason that the generous trunk helps offsets things toward the practical.

Then there’s the shape: powerful and timeless, despite being built on a body shell dating back to the 1976 model year.

That E24 model 6 Series platform was already a few years old when the performance M6 variant first appeared. Europe got theirs starting in 1983, but American consumers had to wait until the 1987 model year. No matter the market, the recipe was similar: In addition to a boost in power and a Getrag fivespeed gearbox, the M6 received stiffer springs, shocks and anti-roll bars. A lowered ride height, trunk spoiler and deep front air dam were among the visual cues. Inside was wall-to-wall leather.

Michelin TRX tires came standard, and these didn’t follow the usual rim diameters; the M6 received a 240/45VR415 tire mounted on a 16.3x7.7-inch wheel. What does that mean? You’re going to have to seek a specialist for replacement rubber, assuming that the car is still wearing its stock wheels. Coker Tire can help, with fresh Michelins in the correct size retailing for about $450 each.

The M6 wasn’t a cheap date back then, either, carrying an MSRP approaching $60,000. Current prices have started to climb, too, with the best ones approaching $55,000. If you act quickly, the rank and file cars are still in the $15,000-$35,000 range.

The first generation M6 was a bit ponderous and significantly slower then the first gen M3, but the engine is one of the best straight 6s ever built and sounds great.

M5 are a bit lighter but quite rare. The M3 (first iteration) are probably still the best bet for enthusiast owners. The E46 version starting in 2000 had the superb S54 engine with 333 bhp and an 8,000 rpm red line.

I have a friend with one who just throws money at it as if it were wood into a fire pit.

Just a little update: Bonhams recently sold one of these for $104,500!

It was really clean, though:

There is one of those under a tarp on the side of a house I walk by every day with my dog. Also has a nice 911 longhood targa in the garage that is an all original gem. Always dug the M6, that BMW I-6 is smooth as silk
