It's hard, because you have to make an investment in equipment. I have about $500 invested in turn plates, toe plates, and a digital caster/camber gauge. It's hard because you don't have a rack to work on. It's a lot of getting up, and down. going back, and forth checking things. I just got tired of paying for a bad job. Plus I have 3 classic cars, so it should save me in the long run.
