I bought my acura in 2007 from a private party with about 160,000 miles on it. Since then it's been extremely reliable, the only thing I have spent money on is brake calipers for rear left wheel. Other than that I have had no issues. My car has now 216000 miles on it and it still feels the same. I would highly recommend acura to anybody who wants to buy a used car.
The only downside is the cost for parts and servicing, Acura parts are extremely expensive to say the least.
