I have been in lust with my 2000 540 sport since our first day of ownership. Now with financing specials and low sales at dealerships, an affordable CPO 2006 550 with sport and cold weather packages has caught my eye. Has anyone moved up and regretted it? I def prefer the e39 styling, but the power and ride of the E60 is addicting! Bev and I drove a leg of the Komen transport from Albany to Maine in one last year, and it was a joy. For those who know of Dave Ramsey, please don't tell him I am considering doing this when being five months from being totally debt free!!
