1998 Boxster S w/ Engine transplant.. good buy? link inside

[jonomo]

Hello,

I talked to a dealer who says he has a 1998 boxster S for sale... he says in 2007 the car had a engine transplant from a 2002 boxster S.. The price is good... but the dealer feels a bit dodgy... he says it's also had a respray and guarantees that it's accident free...

Is there anyway I can check the manufacture date of the motor?

I live in Korea and Porsche prices are rediculous.. and this one is really priced right... here's a link below.. what does everyone think?
