What exactly are you looking for? Accounting software, or parts software? If accounting, a client of mine uses PeachTree Accounting from Sage software and likes it; good interface from what I've seen. If you need parts software, my friend's dad owns a body shop; I can ask him either tomorrow or Monday what he uses and report back to you.

On cost:

PeachTree Accounting 2007 is about ~$1200 for a 5 user license. If you need more than 5 users, PeachTree Quantum is $4000 for 10 users.

Getting a custom system written will cost lots of $$$ and have unique problems and solutions. Probably should stick with commercial software if you're s small shop.
