2013 BMW 5 Series 528i 4dr Sedan (2.0L 4cyl Turbo 8A)
I've owned a 550, 535 and a 328 and by far the 2013 528 is the best BMW I've owned.
You won't know you're driving a 4 cylinder turbo - it is faster than the previous regular 6 cylinder.
Comparing it to my previous 5 series, it is an upgrade in luxury.
The new NAV w/heads up display - Luxury seating package - the Hi-Fi Premium Stereo system and the Oyster/Black interior is beautiful.
