That's fine IF you want to get 4 people in a car but if you don't then why bother.
The GT-R as I said before is a good car for driving like you nicked it, but about as comfortable as sitting on a 1970's roller skate (the sort you used to strap on your shoes)
The XK is a grand tourer, a comfortable barge to cruise in comfort (I don't know about the RS)
Think thats a bit extreme, granted its not the most refined GT cruiser but defintaly not as uncomfortable as your portraying.
The XK is a barge the GT-R is something very special for those in the know
