I break it down this way. Age is a body interior thing. Mileage is a drive train thing. So they are two distinctly different considerations. But both go to make up a good decision.
If the body and interior are in equal condition go for the lesser mileage. If the body/interior on the older one is significantly worn, or the paint is faded/scratched, carpets worn, then the newer but a little higher mileage may be better. As long as the maintenance records check out.
But the question is...how will it look in 5 years of your use? Will the interior/exterior still look good on the old one.
Consider this...the older one with less miles may have spent more time sitting in a nice protective garage. While the newer one with higher mileage, may have actually spent more time in the hot sun, while running the roads. But if in the north the newer one may have spent less time in the salty winter.
A lot of that depends on where the cars were used. The sunny south vs the rusty north. Once you have determined the difference, then weigh it against the price.
Without knowing those details, I would lean toward the much lesser priced lower mileage vehicle.
