Hi all, first post so please be gentle Am looking at a few A3's this week and next week. I am going for the 1.8T as i've heard this is the one to get. Ive noticed some of them have the 'full screen' trip computer. What additional functions does this have over the 'half-sized' version? Also is there a buying guide around, or anything i should be looking for when having a nose around each car? Thanks v much.
