What Mitch said.
With a dead motor you\'ll pay about £1000 maximum, rebuilds are £2-2.5k from the likes of Mr Hayward or Rotary Revs if you\'re up north. A lot die from rear bearing wear because the 5w-30 oil specified from new and the 12k service interval was to appeal to the fleet market rather than to keep the car running sweetly. Run 10w-40 and change the oil at 3k and they\'re good motors. Not Turbo RX7 pokey but they love to rev, the rest of the car hangs together pretty well, the interiors are nice, climate control and Bose Stereos were standard on all UK cars. They can rust around the rear brake light and the rear arches but Mazda did a fair bit to fix this. Mpg is typical rotary but you\'ll get mid-to-high 20s on the motorway. They\'re proper 4 seaters too with a decent size boot. Don\'t be fooled by the "It doesn\'t start warm, it just needs a new starter." line, that\'s a sticking plaster for a low compression motor, if it\'s not a dead motor and they\'re asking more than beer money for it then insist on a hot compression test.
