Im looking at getting around a 2002-2004 model as a daily runner and thought id ask if anyone knows of any common faults and things i should be looking out for when viewing. Will be going to see a few in the next week so need to get as much info as possible please.
Does anyone know on which year the facelift model started as there seems to be mixed opinions when ive looked into it.

Also what changes/improvements did the facelift model actually get?
Ill be getting it re-mapped too hopefully as ive only ever heard good things about re-mapping these. Wheres the best place to go and how much? Will it 'really' improve mpg as well as performance...???
Any info and advice appreciated. Cheers.
