I hope I don't fall for any of those stupid dealer add ons ever again. Totally burned me every time so far. First was the extended warranty on a used truck I bought. The warranty clearly excluded coverage of anything that could possibly go wrong on the truck that would cost over $45 to repair. It was pretty much bumper to bumper, zero coverage.
The next mistake was trusting a kindly old gentleman Ram salesmen that f#@ked me so bad, Fiat/Chrysler/Ram/Dodge/Diamler whatever the f* called it dealership fraud.
Next was the interior and upholstery protection plan or whatever. The salesman pushed and pushed about how it was so crucial we purchase this and what a great deal it was. Well two years later, something sharp actually punctured the leather and the dealership acted like they had no idea how to go about making a claim because they have never felt with this before and it would be a huge can of worms and they really didn't know anything about anything.
