Hi folks,
I'm most interested in the 818s... and...as it turns out, I own a 2004 WRX with a stage 2 tune (Cobb Accessport with turbo-back exhaust).

it has 111k mi and in decent condition

The obvious thing to do would be to sell the WRX and buy a donor... but I've considered keeping it and using mine as the donor.

Thoughts? Considerations?
