I try to do the best job on every car, even my own. I hate being broke down or loseing time on something dumb so I figure just get it right the first time. On some stuff though you are forced to go through a learning procedure. Like on my car, when I got the turbo kit on I had problems with hoses blowing off and IC pipes rattleing, etc etc. I think some of that shit you just have to address as it comes up. I would think on your car that you may have to deal with getting the bugs worked out now but the payoff would be awsome.
