55K, 2015 GTI. Bought used, Don't regret it, has been a fun car and has been very reliable apart from a few issues.
Real Problems (all are common issues found on this forum)
1. VW replaced N80 valve and EVAP Canister under warranty (got check gas cap on dash and sometimes a check engine light that would come and go, very difficult for dealer to diagnose but they replaced it after the 3rd time coming in)
2. Silver Trim around shifter was peeling and was easy to cut yourself (VW replaced under warranty)
3. Lastly, would have to top up coolant every few months or so, very slow decrease, but I recently took into the dealer to run pressure tests, check for leaking , etc. but everything was fine, they recommended a coolant flush though
Again, these are common issues on this forum, and #1 and #3 are the most concerning but VW/dealers have been helpful for the most part in helping address the issue.
