I testdrove one last Saturday.
Was not able to go on the Autobahn but from my first impressions, the M5 is a lot more fun to drive.
Shifting in the R8 is lame but might eed some practice.
The plastic in the console next to the handbrake is horrible (understatement) and in the door sounds very, very cheap.
The leather and stitching is very nice.
The looks attracts a lot of attention, a bit too much for my taste.
Loved the coupe feeling.
Engine sound from inside the car at say up to 4000 rpm is like a sewing machine. I didn't like it. At higher revs pushing the car it sure gets a nice sound. But is subjective.
If it was, with all the extra's, 40% cheaper I would have considerded it. It costs with extras 180k Euros over here. The M5 with extra's 150k Euros.
However my soon to be 9 year old son likes the R8 very much.
Ohh forgot to add. The brakes of the R8 do feel really good.
Amazing...whilst all this sort of thing is subjective ,I would say the following..the Audi build quality is superior to all the recent cars I have owned..(997s,996tt,997tt,M6,AMG sl55),the engine also sounds much better than any of them..and the brakes whilst very powerful are actually too sharp..the interior is far superior to any BMW or Porsche.The only thing I agree with you on is the attention you get..it is staggering..but nice attention..not like driving a ferrari where people curse you.
And did you not get to go on any good roads ? The chassis and handling are what makes the R8 very special.
