My favorite BMWs so far are the 3 series GT, 5 series GT, X4 concept, 3 series sedan base model, X3 (old and new), new X5, X6, new 1 series (if they only gave it bigger headlights...sigh. Bigger headlights = more light at night).
Also, if I had the money I would spend $130K on the new M6. So what if it loses all the comparison reviews? If only they added more fake sounds to it.
They should have 1 series GT and 2 series GT with plastic vents on the side. The back of the GT cars should get bigger with the series. 5 series GT rear > 3 series GT rear and so on.
They should also start a new body type: 2 door sedan and call it the GranSedan.
Finally, they should continue selling 320d masquerading as 328d and 328d as 335d as long as they don't have rusty seats - I hate tetanus injections or injections of any sort.
