IMO the Z is well worth it. I remember working on my car when I did the motor swap from 9AM till 430 AM the next morning day in and day out. I am sure I am not the only one who did the same but I guess its my therapy and once you turn that key, or take that first drive, or drive down the road and get thumbs ups and people telling you nice car. BUT it is truly an expensive car that will have you for sure working on it almost weekly but for us enthusiast we get I guess some thrill out of it all knowing what the final project will bring us.
