Im sorry, but I reckon most would be sporting a permanent erection just sitting in a P1, even pulling it out of your garage would be an event. Thats exactly the point Im getting at, something like a Murcielago will always be reminding you its a supercar, whereas a GTR is only a supercar when you give it the beans.
M135i is a faster car in a straight line ............. but this also illustrates the point above beautifully, M135i feels like a fast 1 series, the 1M feels like something entirely different as soon as you get 20 yards down the road.
Maybe the P1 was a bad example, but it's in a whole other league.
I watch an episode of US Top Gear where the fat one was trying to drive a new Lambo in the city. It's was very uncomfortable because it kept kangarooing each time he went to move forward a bit in traffic. So, although it's more of a supercar than the GTR, it's not as useable as a daily or even in the odd bit of Sunday traffic.
As much as I'd love a Merci or Gallardo, it would get on my nerves if I couldn't use it for icy driving as well, the GTR excels in all aspects, although not as exciting unless pushing it.
The "quote" re the M135 which I think is a BMW ^^^^^^^^^^^^^^^^^^^^^^^^^^^^ was not made by me.
I have not got a clue about BMWs as they have too many geeky numbers and all look the same.
