Done some basic research on this for you ref:model year 2004 passat brochoure, don't be fooled by the highline its a bit of a myth, from what I can gather best trim is Sport, the levels are S, SE, Highline, Sport. The highline and Sport offer diffrent levels eg sport offers sports suspension, optional sports seat, sports s wheel,rain sensor and fogs as standard but th highline offers, leahter as standard, special highline wheels and diffrent levels of equipment. I think you should be looking at a Sport I reckon you'll get all of the above. REMEMBER depending which model year your after will depend on spec levels. Just in the last year the all the models have been spec'd up to sell off old shape so go for it........Rhys said:
P.S I have a 2001 se tinted windows where standard eqiup on mine and cruise can be fitted as an after market for around 100£ using genuine vw parts. Xenon lights where only standard equip on W8 but optional on all other models.
Hope this helps Jay
