Yep they do suffer from chain trouble as Ross said due to wrong oil..Good friend of mine had a 04 one for about 2 years and not a days trouble out of it and he drove her on hard on a daily basis. Lovely comfortable car very solid on the road, only thing I noticed was when ur up around the 3500/4000 mark it used to shake and vibrate like mad, don't know it was just his car or what but other than that I think there a fine car if you pick up the right one.
