I'd bet they're both around mid 16's or so through a quarter. After that the 16v is toast no question, the 104 tears it up through mid and highs. Damndest thing, stock or not, I have never raced against another similar year Mercedes, and never even seen a 16v that wasn't on a lot. I would probably bet on you're car though, only because the European model, US maybe 50/50. 60HP is big difference. The launch is the obvious weak point. And holding the brake and revving, at least on mine, makes it shift to second when I stop burning the wheels, so it doesn't help. Burning the wheels never happened with stock anyway.

Is the european finial drive the same as here? Those are usually so ridiculous luxury car tall. I couldn't stand it. I'll take 80MPH revs at 4500, I dont care.
