Does anybody have any opinions or experience of Passats that they would like to share ?
overrated. expensive to maintain. prone to leaks.
Your missus can't be that bad. What you think of a passat though?

Just swapped a 100bhp 2001 TDi for a 130bhp 2004 Highline TDi model. If you do go for one, make sure you get the more powerful engine - it makes a BIG difference.
Also if you're not going to get a brand new one, the highline models are the best value - they were the run outs of the older shape and as such come with all the optional extras - heated leather seats, upgraded stereo + speakers, alloys, traction control etc....
I've not had a problem with either of mine, but of course YMMV.
