earlier this year I bought my second Z for roughly 16k and "I" felt as though it was worth every penny. I paid the seller's asking price too. When I sold my '90 low mileage unmodified TT 2 years ago, I just broke even since I only owned it for a year and a half and just fixed things that had been neglected. Needless to say I had to be patient and fend off the numerous lowballers. The car I have now is very similar to yours, minus some of the big HP items, and I still think its a great car to drive every single chance I get. IMHO, your car is a great deal since it has been so well maintained and upgraded "responsibly". Best of luck and heaven forbid if you decide to part it out, give me dibs on your brake kit!
