My lhs will build or setup or fix virtually anything. The guys they have working there are very competent, and a lot of the locals will bring in buggys before a race to get it setup better. Ive seen them building kits, restoring vehicles, etc.
Ive had them do soldering and build shocks for me, but I usually just do everything myself. But they do a much cleaner solder job than I can for super cheap.
