Really lucky when it comes to cars for legroom.I am of Chris Harris stature (but not ability); 5'8", 11.5 stone. I fit in anything!
Being of reduced stature isn't often handy but it has its uses. Handy for surfing too!
The roomiest car for legroom for me was my Corvette C5 and also funnily enough one of the most comfortable.
At the moment my cars are a Range Rover Sport & a Mercedes 1992 e500 v8,the model which was changed around by Porsche at their Zufflingen Factory.
Plus hopefully a T6 when they will eventually accept new orders, now likely to be after June 1st with their updated prices likely 4%
