I bought a Chrysler Maxicare from the dealer for $1650. It has paid for itself in one year twice over. Contact todk64 on this forum. He will get you one for the best price most members have found. I've have a dealer with an excellent service department and there are a couple of others in the area. If you have a third-party warranty, you can take your XF to an MB shop, but no MB dealership will work on them, at least no dealership that I've found in the Washington, DC metro area. I live a couple of miles from the 4th largest in the country and the only thing they will do with a XF is take it in on trade; no service.
