I don't know what happened to my last post, so I'll post again. There seem to be lots of people spewing opinions that have never owned a Vette. I had an 02 Z06, bought with 28k miles, sold at 32k miles.
Fuel costs compared to your Benz? Vette wins easily. I averaged 24 in town, and 28 on my one and only trip to NY, doing around 80. Gotta love 6th gear. Insurance? My 04 F350 costs more to insure than the Vette. I posted to do tons of research on Corvette Forum, as did someone else. There are quirks to them all, hopefully they have been fixed. More annoyances than anything. Want to know why Vette owners wave at each other? Because they know they got screwed by GM too...
