Re: High Mileage
Read back through this forum for threads asking for advice buying used XFs. It doesn't matter whether they have 10k or 100k, the advice is consistent. Only the risk is higher -- offset by cheaper price -- on a high mileage vehicle. Good luck.
PS - General concensus is that if the XF was well-maintained and not abused, it should be good for a lot of miles. These MB engines are pretty much rock-solid.
