Evan, I view building a car a bit like working on the boat. It's nice to have stuff done for you (sometimes to save time & whatnot) but unless you knew how but didn't have time, when you break at the track you're towing it back and waiting to find out what's wrong, rather than potentially fixing trackside.
On the boat it's worse- if you can't figure it out or fix it you can be in a world of hurt. I'm constantly surprised by adults who can't do simple mechanical or construction type tasks. I know a few people who I swear aside from pushing paper their skills run to "watch tv" /ubbthreads/images/graemlins/laugh.gif
