I'm going through the same right now... do I get a E92 M3 or C6 Z06.
The car will see HPDEs at least 5-6 times a year... which is concerning to me given these engine failures (valve guide) are becoming far too common nowadays, specially to tracked cars.
Having owned a C5Z (and modded to 440rwhp), yes the power can be very intoxicating. It'll be a DD, but my commute is easy and short... I have been leaning towards the Z, but the engine issues are worrisome.
Straight-line speed is not my priority, though torque is always fun. The handling, the fun aspect, is what I'm looking for. We'll see...
