When considering why I was looking to change out the RS5 it was mainly because I'm not getting the benefit of the car as I used it as a daily driver. So generally spending most of the time plodding through traffic on the commute and when I did get to a back road for some spirited driving the road conditions have generally been pi$$ poor for what feels like forever. So in steps the Jeep, fitted with a tuning box I've managed to take 2 seconds off the 0-62 time, down from a stock 10.6s to around 8.1s (trust me, you don't want to be going fast in a box with a high centre of gravity!). It'll tow my bikes when I need and will get me out and about in all weathers. The finish is not bad and it's got all the gadgets I need (decent stereo, iPod interface, bluetooth h/f etc.) and if i really want to go 'super gay' I can even take the roof off in sections!
Now the really big benefit is when the sun is occasionally shining I can now jump in the RS5 and after driving the Jeep it feels like the proverbial 'rocket ship' again. Another benefit is now that I'm driving it less I don't have to clean it as much so can keep it nice and shiny in the garage and there's very little miles going on it which should/might help residuals

The R8 V10 decision is now deferred until 2015 when hopefully the RS5 B9 hits the streets (hopefully with the 4.0l twin turbo) and I can make a proper comparison. Might even throw the new car net a bit wider and take a look at Aston's and Fezza's.
Happy days indeed.
