2008 BMW 5 Series 535i 4dr Sedan (3.0L 6cyl Turbo 6M)
Previous owner of '03 525i. The new model gives you the best of both worlds. Luxurious and sporty. Smoothier, quietier, more power, and more elegant.
Clear head-lights, keyless entry, sports package, premium package-contouring seats and lighting system, larger display screen, new and improved on-board computer (navigation, bluetooth, etc).
Cannot think of any major improvements needed. However, I do wish the new model has more obvious new exterior designs. The only differences are subtle (noticeable by BMW experts), which makes it difficult to distinguish the older models and the newest '08 model.
