i took my 90 for it mot yesterday and it passed .
slight leak on exhurst downpipe and a slight oil leak (which they all do).
and the emissions were .4 (point 4).
Replaced the downpipe today as the problem was a split pipe (could have welded it but for 15 notes for a new on it ant worth it and it been bodged by someone before).
mot tester said it was a good example for a 20 year old 90 :D
not going to fix oil leak as it kept my chassie rust free for the last 10 years or so...lol
