Ditto on sales people being rather clueless. The guy who sold me the Traverse was trying to tell me adding the factory towing package (it was used) just involves bolting on the trailer hitch and plugging in the wiring harness. Uh no, a little more than that; try multiple wiring harnesses, a different radiator, external trans oil cooler, tow mode switch for the dash, a couple of relays, new fuse block under the hood... On the other hand, he was impressed I had done all the maintenance on the Honda CR-V I was trading in and had kept all the records since it was new. He wanted to buy it for his daughter, and while she was skeptical of it already having 130,000 miles on it, he was trying to convince her "Believe me, you would want this guy's car, he took good care of it.".
I do all the routine stuff myself, except tires and alignments. Brakes, rotations, fluid changes, spark plugs, most minor repairs I can do myself. I did my own alignment on the Midget since the only adjustment it has is toe in and wasn't hard to do with some improvised tools.
