i just picked up a 93 subaru legacy wagon....does anybody know a website or a place in the sf bayarea that has aftermarket parts/accessories???

haha no offense dude but your the exact same way I was when I first started moding my Subaru Legacy ( also a 93 wagon). A good portion of your mods will have to be custom, however a lot of suspension parts off of the first generation Impreza and second generation Legacy's are a direct fit for our first generation Legacy's. You're gonna have to start doing some research man and find out what is out there for those vehicles that are compatable for what you want to do with your Legacy.

check out ebay hella stuff for a good price
