Considering trading in my M3 (not THAT M3) for a Model S. Had a few questions: Are the prices lowballed so bad such that the tax savings do not make up for the shortfall? Taxes here are nearly 10% so I'm guessing Tesla would have to offer a pretty terrible number for it not to be worth it for the convenience factor. Is it worth trying Carmax et al to get an appraisal? My sales guy told me their process is basically sending the car info out to 100+ paarties (incl. Carmax) and best quote wins - so it seems this would be a pointless step - but I'd be interested to know if anyone has found better trade-in quotes despite the Tesla process. I have a small (city driving) nick on the bumper of the car I'm trading in. Is it worth fixing for $500 or leaving it as is for the appraisal? Not sure how much of an impact it has on the appraisal number.
