should I trade my Z for m3?

Pharmacist

Personally I'd keep the Z and get an Evo. 2 fast cars always better than 1. This way you can tune both of them and if one breaks, you have the other one to drive while waiting for repairs. Not to mention you get to enjoy the driving experiences of rwd vs awd, 2 dr vs 4 dr, n/a vs turbocharged, manual gearbox vs double clutch automated( assuming you get the MR).

The M3 is a very nice car and it's a lot more luxurious and refined than the z. But it's not really as much of a step up in performance as some people make them out to be. You get marginal improvements in handling and acceleration, but that's it. And if you're hungry for more power and acceleration, keep in mind the M3 only has 414 hp and not much of an aftermarket to support it. This, coupled with high repair costs of german cars without a warranty may make you forever stuck with the stock performance of the M3.
