As a former C5Z owner i can tell you some pros and cons... The drivetrain is GREAT!! Has lots of power and it handles AMAZING its BY FAR the best handling car ive owned period. They are fairly reliable and mine would get 29-30mpg on the highway cruising. A very fun car to drive.

However it is made by GM which means the build quality isnt the best. One common thing to look out for is water leakage, mine would leak like the titanic when it rained... this is due to a defect when GM built them they used a type of glue to attach the roof which becomes hardened over time and eventually cracks and causes water leaks. (common issue on all FRC's) they only way to fix this properly is to REMOVE the whole roof and re glue it back on. Also there are electrical gremlins to deal with such as the gas gauge that will only read half way because the vette has two saddlebag tanks and uses a pump to transfer gas from one tank to the other and the sensor goes out in one or the transfer pump and its a PITA to fix it. Mine also had some wierd issues with the dash cluster (i think caused by the water leak) sometimes while driving down the highway all my gauges would just die and drop to zero for no reason and then come back to normal a few seconds later..... the interior feels very cheaply made also its like sitting in a cavalier.

Bottom line is i would have another as a weekend car or track car but i wouldnt want it as my only car id still need a daily. However the C6Z is a whole different animal.

Here is a pic of mine.
