[Vwdiesel] newer tdi's

[cass]

hi kids.
ok..so hope this question doesn't start a war... ;o)
have another friend  looking at vw tdis FINALLY..
course...i know nothing bout newer diesels.
they want one from 2000  or newer.
now..heres that trick question..
is there a 'better' year to point them to?
or a year or production to stay away from?
anything in particular to look at?
they really want a wagon..

thanks for any suggestions on this..
as im a lil ignorant round cars 
that have more then 8 wires to engine  :o)
