Your wife can drive a 650 the same as a 640. Unless she likes to mash her foot at stoplights she will never know the difference. As a very general matter the 640 engine is considered to be more reliable, but I have had no issues and there are not a lot of posts here to back that up after 2012s or 13s. The asking price is ok for that year and miles, but like most asking prices there is probably room to negotiate. I would not necessarily assume it needs a lot of work, but if you are the type to pay a dealer for an "inspection" then I guess you should figure in some additional cash. It is not loaded, but optioned ok. I personally do not like the all black look, but if you do then nothing jumps out that would suggest you should not buy it.
