The 540i M-Sport we posted this week posed some interesting questions in regards to the E39s available on the market. The 540i has a good engine and lots of choice bits, but the E39 M5 has the engine and even more choice performance parts. I asked why you wouldn’t just spend a little more to get the Big Daddy, and today we have an example of just how attainable the E39 M5 is these days. Originally owned by the CEO of the Tire Rack, this M5 has just about everything you’d want when looking for a used car – huge Autocheck score, not that many miles (but enough to bring the price down a little), well-informed owners, and overall great condition. Is it worth $16,500? In my eyes, hell yes.
