Cobra, I've had a Cobra ('96) and found it to be trouble-free. I've had three Vipers, a Gen I, a II and a III. All were as reliable as any car I've ever owned. You wouldn't be at all disappointed with the upkeep or maintenance of the Viper, except for the extra charge for oil changes (which I prefer to do myself for half the price), and a rare wheel alignment (I've done one in all my experience, and that on a used car, as a precaution.) I would take out the best extended warranty from Dodge, not from an independent co., just as an insurance policy against a motor failure if you are tracking without the oil swingtube and high pressure oil pump from the Competition Coupe. I don't have much trouble with replacing air in the gas tank, as I have gotten as much as 21.9 in a Gen III, driving 70-80 on the interstate. It's city driving, city at redlights and constantly accelerating and braking in traffic that brings down the MPG. This is one truly tough car which can be rungout without fear of breaking. I never tracked my Gen III, but I had a blast tracking my Gen II GTS at places like Road Atlanta, Texas World Speedway, No Problem Raceway, etc. Dragracing caused no problems,either. Good luck.
