Hi, i'm looking to buy an A4 TDi estate in the very near future, however I must confess to being a little confused on specifications. I've seen the S-Line which I like but I gather they don't come with cruise control which is something i'd really like. Also i've seen an SE and SE TDV but can't fathom the differences between these and the S Line apart from the wheels. I'm really after cruise control, leather and preferably Sat Nav which I don't think are standard on any spec. Is there a site which is 100% correct as to trim levels as I keep getting different information? Thanks for any help and apologies if this has been covered before.
