To be honest: that’s not a big deal to spend less than 4k during that time. I have a 2011' BMW 1series and have had NO SINGLE ISSUE during 100.000 kilometers (equivalent to about 65.000 miles). It now has 120.000 kilometers and guess what — no issue (ok, there was a light that needed to be changed for €10). Except yearly maintenance at about €500.
I spent on my other car (BMW 5series) about 5–6k for service and maintenance over a distance of 200,000 kilometers.
So, 4k on 65,000 miles really is no big deal.
