I have a friend that is looking into a used coupe and I was wondering if anyone has a preference and why? Is there any service or repair issue differences?
650 is newer Depends on what they want to spend. There's some great deals out there on '07 and '08 650s. The newer the model, the more bells and whistles and a few small things fixed like getting traffic updates in Nav system AND HD radio together. Something that didn't work before early 2007 manufactured 650s.
I shopped both and purchased a CPO 645. I preferred the 645 because: 1) I hate the new style shifter (steptronic). 2) I'd rather just turn a key to start a car rather than insert a key and push a button. 3) Better gas mileage--I consistently average 20.4 mpg.
