Reliability wise these cars are well built. The majority of problems are linked to people doing things they should not. Like broken driveshafts. My mom is on her second F-Body and has no major problems. I am a mechanic and these cars have the same reliability as any other car, not taking into account the owner 😉
Now insurance is going to be higher. Again see owner's. The corvette is one of the highest death rates for owners, has been #1 for a long time. Not because the car is unsafe, just the way SOME owners drive them. People get cars that they can't handle. I drive my Moms z28 and when my parents are with me they think I am going to wreck it but I know what the car can and cannot do. My parents don't. I can handle just about anything out there. I fix them, sup them up, and drive them.
But the F-Bodies are the best bang for your buck. And if you can keep the tires from slipping you can get these just under 5sec's to 60mph. How you like those apples 🙂
