Just learning about corvettes so let’s say on a 2003 year corvette what is the differences between a reg corvette and a Z06 of the same year ? And how much more is a used Z06 worth than a used regular corvette of the same year ?(ball park $$$ in same condition of coarse) and is the Z06 worth the extra $$$$ & will the Z06 hold more value down the road in years to come ?
