I had many dilemas and many configurations when building my Sportback and the budget goal posts moved several times, but ultimatley I got to a point where every config had a core set of must haves. Mine were: S-Line/TFSI Engine: COD definitely appealed and drove me towards Audi as did the TFSI (turbo) engine. The extra power, performace and technology appealed to me compared to the basic 1.4, whic is an excellent engine. A lot of the reasons I chose the excellent 2.2 diesel engine really. Comfort pack: Lot of bang for buck, despite the fact that many should be standard kit in my opinion (Crusie control, auto lights/wipers). Getting the reversing function, accoustic glass and auto mirror was a bonus I guess, but not must haves. Paint: Once I settled on S-Line it couldn't get a block paint, although the £550 saving appealed as did brilliant red, if going for a sport this would have been the colour of choice I think. Settled on Daytona. Heated Seats: This was a big one for me having had a Civic, which has the worst ever heater and doing short journeys in the winter was not to a pleasant experience. I know this is an unusual one for most, but big deal for me. Audi Sound: Listned to standard, B&O and Audi sound and decided the middle ground upgrade worth the extra to do justice to the MMI and having all that music on tap + Dab. First dropped: Staying in budget the following went quickly: Sat Nav (Co Pilot on S3 more than enough for me at £20) Privacy Glass Advanced Key Thinking it would be good to see others logic on how they ended up with the ideal build when budget constainsts meant you could not have everything. Pretty happy with my selections, maybe should have added hold assist, nut missed the cut off when I tried to add it on after reading this forum.
