after having rs4 v8 for one year I have to make decision (rs4 is already sold). I know X6 and R8 are totaly different cars but i have to decide if take supersport or SUV (and for me X6 is the most SPORT UV). I would like to know opinions of others. I dont want 2 cars. I already had and dont like it.
40k kms per year, no child etc

X6 4.0D
+ new car - warranty
+ fuel consumption
+ not too much provocative as r8
+ comfort
- diesel, even the best 6 cylinder, still diesel
- not sporty car
R8 V8
+ sport car
+ love V8 sound
+ feeling of driving
- fuel consumption, but who cares

- servicing (s tronic need replace every 50k kms; lame carbonizing of exhaust valves etc.)
- 2 seats, no space for my RC car

- speeding in my country is crime
- not new car, no warranty
Thank you and have nice day
Garry
