I've test driven a few 545i, 535d and 745i over the last week and I've got my mind set on a BMW this time (for car number 23). I'm already thinking that my car number 24 (in a year or two's time) will be an A5/S5. I've set my budget at about $45k during the current search. I've got a 2004 545i fully loaded black/black with only 30,000 miles well in budget that I drove yesterday. Those air-cooled seats are awesome. I've also got a 38,000 mile 745i with every option imaginable under consideration that just sneaks under budget.
