My 15-year-old Mercedes E-Class estate finally got scrapped last year, so I treated myself to an E63 AMG estate. I love the car and I can still get masses of stuff inside and on the roof, but I can't legally fit a tow-bar, even if I wanted to. I need a car capable of towing a horsebox or car trailer that doesn't cost too much and is fairly simple to maintain myself. Even my 15-year-old Mercedes had so many complicated electronics that repairs became prohibitively expensive. I'm currently looking at old Land Rovers, but maybe there is something more practical (and comfortable). Any suggestions?
