First off, all dealerships are full disclosure. Its against the law for a dealership to hide anything. Secondly, you can trade in your lease but you will take a huge hit since you are only financing 1/2 of the car. Add the fact that the current 2012 1 series is soon to be outdated with the release of the new 1er come next year. If I were you I'd have them find me another car, although it may be too late already. And those premium tire and wheel packages cost pennys to the dealer.
