So my boyfriend is going to help some friends with their car today. Does anyone know of a GT-like community either on Gawker or elsewhere on the web for car advice?

He posted on Reddit, and Youtube car guy he follows in hopes of an answer. He's googling different things, trying to make deductions like Sherlock for cars. (It's actually quite sexy and I'd be pouncing him if I didn't feel like crap on toast).

ETA: Didn't realize the boyfriend had to leave and meet the friends 5 minutes after I posted. We're in an apartment and so are our friends so he's working on the car at his parent's house. I am going to bookmark this, for when he comes home. He'll probably be really happy for the help when he gets home and to have car people in the future.
