For me it's not so much the performance etc. Let's be honest, driving the C7 Z07 at 8/10ths is probably unrealistic for most, particularly on the street. So the question becomes, do you really need to be shelling out all that extra $$$ for the latest cool depreciating asset? Hmmmm.....It's tempting.......
Yes in these practical terms you are 100% right. But when it comes to Corvettes and Hummers I loose my perspective on practical. We / I spend life being responsible and practical about everything but these are my toys so different rules apply.
