I bought my '82 300 D turbo last January as a commuter, and so far it has done me very well, I went from spending 100 bucks a week driving my duramax powered chevy to just 40 bucks a week.
My question is what should this cars 0-60 mph time be? Currently it takes 18 seconds, my pickup will do it in around 8 seconds, quicker if my hypertech tuner is on level III.

Is 18 seconds about the norm for this car?

Thanks;
Rod
