Rx-8

So i'm looking at getting a RX-8. I found one for a good deal but the car has low compression. Its a 2005 really clean car has been kept under a tarp in a garage when the owner went out on duty and he wants to sell now that he knows it has low compression. The compressions were @ 250 (6.6 6.5 6.8), (6.5 6.5 6.3). What would you think a good price would be for the car and would you think it would be just seals or possibly something else?



And would you suggest just a engine rebuild??



Thanks
