Here’s my qualifications: I have an 89 383 self-engineered Corvette and a 98 C5 Supercharged base coupe in the garage. The next door neighbor has 2(!) C6 Z06’s and a C6 6-speed coupe, all three I’ve driven. I’ve listened to their feedback and it jives with my experiences:
These are the best vehicles, mechanically, that you can buy for the money. Period. At 10/10ths, there’s not vehicle anywhere that’ll beat it, with the simple variable of driver’s skill thrown into the mix.
While they’re the biggest bang for the buck, they also make a tenth the number of vehicles a year than, say, Honda Accords. Because of that, there may be little mechanical oddities. Things like ‘if you don’t leave the stick in reverse, it wears down the battery’, or in my case ‘The seat doesn’t remember where my memory position is’.
In that specific case, it’s not worth it to me to determine if it’s the Body Control Module, or the Left Door Control Module or the wiring harness that’s at fault. I just live with it.
Based on your perspective, those oddities can be the difference between ‘eh, it’s a car with some quirks’ and ‘this is the worst piece of crap I’ve ever owned.’
The truth of the matter is: It’s an emotional perception. If you want an Audi A5, then every little quirk will be a reminder you didn’t buy an Audi…but if you wanted a Vette and bought an Audi, the same thing will happen…because I guarantee you, both cars will have quirks and the ‘X is better than Y’ is really no more than brand chest thumping.
How can I say this, after saying the Vette is mechanically the best bang for the buck? Because 99.9999% of the time, you won’t be driving the car at 10/10ths. And at 6/10ths, the cars will perform similarly. There are a hadnful of people that can get a 7:39 on the Nurburgring driving a Vette. You (and I) are not those people. 
The C6 is a tremendous improvement over our C5…But they’re nearly the same cars. Same brakes, same chassis, same motor, same skin…only every single bit of the puzzle has been polished a bit. Having driven both, I’d not sell my C5 for a C6…it’s not a big enough improvement for the car payment…even though the C6 is an improvement, it’s not a big enough improvement for me to make the jump. (or in the case of the Z06, selling a lung, kidney, arm and leg.)
Corvettes are the technology testing ground for GM. Serpentine belts, Inter-module network, hydroformed rails, balsa-composite floorboards, throttle by wire…all came out in the Corvette first. That technology is great when it works, and not so great when it doesn’t (My key fob has a mercury switch…the idea was that the car would unlock when you walked up to it. I turned it off after the first twenty minutes of listening to the car lock and unlock while I was puttering around in the garage. The NEW system is quite an improvement.)
The current Z06 is useless in first and second gear. If you stand on it, it’ll be spending it’s whole time trying to keep you going straight and pulling back on the gas to keep you on the road. The Next King of the Hill Corvette has another 110 hp on top of that. That means it’ll be able to break traction in THIRD gear at 100 mph. While I approve of the technology, it strikes me as a little irresponsible that GM’s only requirement for the purchase of that car is adequate funding.
Lastly, in going from your Saturn to this car: Your insurance will triple, your tire expenses will triple (at least until you replace that first set…then you’ll slow down), your fuel costs may jump (or not. 436 hp and 28 mpg highway is a testament to GM’s powertrain folks), and you’ll find yourself coming up with excuses to just go out and drive.
As far as using up a car with dropped clutch starts and bouncing off the revv limiter, you have to be ABUSING THE HELL out of a Corvette to break it. I mean stupid stupid stuff. The car is designed for racing abuse. Every single one off the assembly line. IF you’re gonna campaign it in serious competition, yeah, you’ll need more cooling, different tires, and different brakepads, but for 99.999% of the people out there - if you can break it, you did something really stupid.
What the hell, it’s just a car, it not like you won’t own more in the future. If you wanna get it, and you can afford the payment, what’s the worst that can happen?
(And if you do, get your keester to a driving school, I don’t want you breaking your car!)
