How much should a be Boxster 2005 with 6,000 miles
 

I got offered a Boxter 2005 , with 6,000 miles
Xenox
Triptronic with shifters in the steering wheel.
Silver in great condition with 1 year warranty

For $56,000 here in Costa Rica (We pay 50% import duty)
A car has to be $37,000 in USA .

Another option is a 2003 with 13,000 miles for $42,000
Manual gearbox

According to Kelly Blue Book :

2005 : Retail $44,905 Private $39,410 Trade $36,310

2003 : Retail $31,775 Private $27,505 Trade $25,060

So, I would say the 2003 is a better deal...

Hope this helps...
