Well, I collected my RS4 from Rob at Camberley this afternoon after driving around in a 2011 B8 S4 saloon for 2 weeks and, whilst I still grinned when I started the old girl up (the S4 sounds pretty pants tbh), it immediately felt it's age after the S4....It was an enjoyable drive back home but there were several things about the newer B8 S4 that I missed and for me it highlighted that the new RS4, whilst not looking as good as my B7 avant from the pictures, will be a great overall car for my needs and I look forward to seeing the price list and of course driving one in the flesh...
I also have a test drive of an Alpina D5 with Sytner in a few weeks which will be v interesting (I had a D3 for 12 months a few years ago and it was a cracking car) but the RS4 ticks more boxes at the moment....
I am very conscious that I may be turning into an old fart by enjoying a slightly more 'comfortable ride' and loving the S-Tronic box of the S4 but I'm sure as hell not considering a picasso at this stage......
