Damnit...

I'm getting the bug again... NA or NB this time... sigh.

There is a great deal on an 01 NB that is pretty much ready-to-track. I think you could get it for a little over $6k, and it'd cost closer to $8-9k to build it from scratch. They guy who owns it knows his stuff, and John Wags built the AST's for it.

I am as well. I've been driving my RX350 for a year and a half and REALLY need a sports car again.

Think I'm going to do an NB...
