how many miles should I expect to get on a 2010 honda crv

IF it was well taken care of you could easily go to 200,000 or higher but as always have a mechanic check it out before buying.

Ask yourself how many miles a year you drive, the loan term and do the math. Make sure it won't wear out before the loan is paid off.

250,k if the it was taken care of, maybe 300 , but after that you will have to over haul.
