I've only had 2 MOTs on my 27yr old D1, get a poxy advisory every MOT though, not for anything like rust but because my Disco was converted to a commercial vehicle in it's lifetime in Belgium and only has 2 seats, 3 door mind with an ally bulkhead behind the front seats but for some strange reason I get the "rear seat belts not present at time of test" advisory even though there is no way to fit the seats ( at present anyways), pizzes me right off, but so long as that's all there is to worry about then I should be happy.
Failed the last one on a ball joint and where I hadn't set the lock stops properly after pulling the swivel housings about the fronts were rubbing the radius arms on full lock.
If I fail the next one after all the work I've done on it I'm going to be major league pizzed off.
