04 996 40th anniversary buying advice
 

I'm looking at buying a 2004 996 40th anniversary x51 AE40 Jahre coupe. The car had a engine swap at 48k due to ims failure and now has 95k at a cost of 22k at the dealer with records. The car has a new clutch and a full service and appears to be in excellent condition. The owner has extensive records. Blue book is around 24k and i know that is just a guide but is the asking price of 31k too much? Any advice would be greatly appreciated. Thanks
