2007 BMW 5 Series Sedan 525i 4dr Sedan (3.0L 6cyl 6M)
An economical BMW?
 We bought a base '07 525i with 19k miles through the BMW CPO program in May 2008.  We liked the looks, practicality, and BMW performance at a reasonable price.  The scheduled maintenance program and warranty were icing on the cake.  Over the last two and a half years, we have found that the combination of reliability, low maintenance costs, and amazingly good fuel mileage (consistently 20 city, 33 highway MPG) has made this a very economical car.  It's a typical German cruiser on the interstate(autobahn) -- fast, smooth, and tracks beautifully. As a result of our experience, we have designated this car our secret "economy car" in luxury car clothes.  I will consider BMW CPO again.
