No surprise here:
Honda Accord
Note in the sentence what he said is the key to longevity

.
It sometimes amazes me when the first thing ppl ask me in regards to their "service" on their MB and BMW is how much is it going to cost. Had a lady ask me the other day in regards to a late model 528i. I told her the oil alone is going to run $40. I guess she has been reading about the $19.99 oil changes at the quick lube place

. If they can't afford to maintain these nice, expensive new cars by the book then they should be driving a Honda. I am of the opinion that you can get any MB, BMW, Honda (just to name a few) to a million miles if you have a proper maintence procedure.
