In 2 years i will sell all my bikes...

I think that there is only one vehicle that would make you happy, and it would also be great on your country estates, the AMG65 G-Wagon V12.

 
Just get a 2016 Challenger Hellcat and keep a couple bikes and have warranty!
 
Ooh, cars! You need three or more separate lists, judging on your first listing, all are excellent cars.
Lucky you to be able to only be worried about the purchase price and, I see you are aware as well, of maintenance costs. Over here you would pay any of these cars again in five years in form of taxes and insurance to the man.

Never looked at a GT-R?
 
I don't know. The price of new and used cars has sky rocketed here in the last year. I would say wait a year but I'm thinking here in the USA the prices will be even higher. In California you get screwed in Taxes and then every year in Registration fees. The Mercedes registration would probably be $3K-4K a year easy. Pick a good one with pics.
 
That one is the one my wife likes, but out of my league for now plus, i dont like it
