Would You trade???

[Cisc0]

Greetings all,

I am in a semi bind. I currently own a 2002 3.0i with 87k miles, no body work, no tranny or engine problems just the usual maintenance fixes (cv boot, control arm bushings, and all preventative maintenance done). I am being offered a trade for a 2003 4.6is with 117k miles, estoril blue with no previous body work but owner has no records of maintenance. Also it has had a tranny rebuilt at 90k according to owner. I drove it and it feels nice, but it has that dreaded "lurch". Owner wants to trade for my '02 + $6k cash. Here is a blackberry picture of the Estoril. I am going to have my friend, who works on mine to inspect it and tell me what he finds.

What would you do???
