I don't think this question has a firm answer, but I sold my garage queen and want to get a car dedicated to Autocross and HPDEs. I see lots of higher mileage E36s for 5 - 7k. I know there are a ton of x-factors at this age in a cars life, but all things being equal and assuming the suspension is probably tired, am I better off getting a 32x and really tightening it up, or going with the M3 that was built for this type of activity, but at this price point, will have higher mileage and the chance that it's been rode hard and put away wet?

Any thoughts or comments are appreciated.

Thanks,
Brian
