Golf carts use CVT's as well.
IMHO the fact of the matter is MOST mechanics are grease monkeys. Some do a few things well some are GREAT al all sorts of things, and others just do it because they can not do anything at all.
I've said this a thousand times... I've been a mechanic of one sort or another for most of my life, and I can count the really great mechanics I have met on one hand. It's an aptitude that goes way beyond classes or school room learning. A great mechanic can see what is happening and why before he even see's the machine.
You don't come across these people every day, and dealerships are no where near having enough of these guys. Actually dealerships generally get the monkeys that mess up an oil change, or the guy that can recite every part number from a 1979 Honda GoldWing but be completely lost under the plastics of a scooter.
Just my opinions
