When these cars were released to the US in 1986 the fuel computer in about 500 of them caused excessive emissions!! MB had a recall to replace them. Most cars lost 4-5 rear wheel HP!
That computer hasn't been avail in the US for over 10 years!!

I don't even have the computer hooked up in my racecar.
