I dont have any personal experience of them but my OH is the after sales manager for a few dealers, one being landrover. They are currently binning landrover because of the constant problems. He says there the worst vehicle on the road.
Pretty much anything Japanese made, German (or with German DNA like Seat, etc), but maybe excluding Opel (re-badged Vauxhall). IMHO stay away from French, Italian, and Japanese branded stuff made in UK (Nissan).
I hope more members contribute as my prejudices, based on personal experience mind you, are beginning to show again!
