Looking at a very clean 535iT w/ 84,000 miles. Puget Sound area, car originally from NJ. Dealer is asking $18,900 will sell for maybe $17,800. Records only from last 2 1/2 years,(well-maintained) serviced by current dealer. Whaddya think? Seems pricey to me. Car comes with one month or 1000 mi. limited warranty. Thanks for your input.
