My ZR-1 was a 91. I really enjoyed the car but was just ready for something different. The car had unbelievable power though. It could literally do 50 mph burn outs, not that I would know....
I paid right around $30K for the Boxster. I was a 2nd owner car, window sticker was $77K new. It is fully documented with all service history. The local dealer was very helpful with disclosing all of the records after the owner agreed.
The previous owner is really a good guy. He even threw in his hard top hoist, 2nd set of floor mats, and a key ring. They were selling it because of their baby on the way. Don't feel too bad for them though, the new Cayenne S sitting in the drive is a decent replacement.
