Corvette C5 or C6 ?

Hello together. Actually I wanted to buy a US classic car, but after test drive and ample consideration I came to the decision, that a young car is probably the better decision, because I just missed the acceleration with the V8 oldies. Now I got a little into the Corvette C5 and already know the vehicle a little, because a friend drives a C5 and this has really impressive driving performance. Now to my questions : I have f The C5 is almost always more expensive than the C6. What is the reason for this ? I personally like the C5 also much better optically, because the folding headlights simply look sporty. Are there other reasons why the C5 is mostly more expensive ? And which engine would you recommend ? LS1 or the LS6 ? Is there anything you should consider when buying a C5 ? All models, which I currently have in mind, have a mileage of 40,000-80.000 KM and have been They look as if they were just running off the line. Nevertheless, there are certainly things to watch out for? Look forward to your feedback. Greetings from Switzerland Andreas
