I get the same feeling. If your gonna "show it" I'm gonna pick it apart. I won't say anything but positivism if it warrants it if they aint a dickhead.
If the guy did his own work on the car and did what he could and like you said not an *** then yea. If they had someone else do it and still a nice guy then not gonna tear it apart.
I keep my opinion to myself but you guys are good friends and I share my opinion here cause your to far away to kick me. lol
