If you only plan on driving 10K miles a year, you could probably get 5 to 10 good years out of the 2016 I'd think. If your use case is higher though (say more like 15 to 20K miles a year), the low mileage vehicle may be the better buy despite the higher price. The only thing that would worry me about a 9 year old vehicle with only 6800 miles is that I'd wonder if it was really serviced at all (considering the first oil change isn't even called for until 10K). I'd probably want to flush literally every fluid in it upon receipt.
