Yea, I don't fully understand tax liabilities when it comes to selling cars. If you sell it for less than the original purchase price, it's a loss, so you don't have to report it. But if I sell it for more, which is the point of the exercise, then... I'll pay income taxes? Or sales taxes? And is it only on the amount above and beyond the purchase price? As for registration costs, isn't that generally the purchaser's responsibility? Since I'll be buying from a dealer, he'll have it registered to me each time, so I'm not dealing with that expense (except for the $600 flat rate I pay him each car). Also, I'm looking to get preapproved for a car loan from USAA. And I'll be buying used cars, but if they're from dealerships, does that mean that they've gone through some sort of minimal servicing? Are dealers, at these dealer-only auctions, buying these cars blind?
