Ok I'm back with more questions, been for a 2 hour test drive this morning, which has confirmed how much I like the car but has thrown up a couple of things. I have a re-currant back problem, which several years ago was made so bad by the car I was driving I had to sell it as I was in constant pain. I drove a level 2 this morning, which after 2 hours made me think I may have a problem (which is why I wanted a 24 hour test drive). I understand the level 3 has lumbar support. Does anyone who has a level 3 but has driven a level 2 know if the seats are more supportive, particularly towards the bottom of the seat back? Secondly I was very suprised that such a lovely car didn't have adjustable height seat belts, again are they the same on the level 3. Thanks, its very difficult buying a car when you can't try the different spec's.
