Hi Chaps, been lurking on this for a while now reading anything and everything to do with the Model X. Took a 24hr test drive last week and was very impressed, so much so that after dropping the car off I resolved to try and buy one. I have done the sums and it works out a similar cost to buying a £35k cheaper Q7 over a 4 year period which is the car I nearly bought before trying the X. I'm coming from a BMW 535d M Sport which is rammed with extras so I'm used to comfort seats, auto wipers, great ambient lighting at night, nappa leather seats, excellent rolling refinement etc. But, 90% of my driving is around town and for short trips so it botheres me firing up a 3.0l turbo engine to go down the road, I know its doing the car no good and my fuel economy is rubbish with a cold diesel engine. So, in spite of the lack of premium polish I resolved to get one, I love the technology, the power and the autopilot is great although the nag is killing me and I did get banned once... I was minutes away from leaving a deposit however I stipulated that I wanted to try it on 20" wheels to assess comfort and also check luggage capacity. I turned up today again with my suitcases in my wifes car and with one rear seat down it blitzed the luggage test swallowing 6 suitcases with room for more. I then took it on a 30+ mile trip which flew by due to AP and shopped for a number of hours, I was fairly comfortable on the first 24hr test drive but couldn't get comfortable on this one. I fiddled endlessly with the seat and still no joy. The journey back was hellish, rain and heavy traffic and the car was calming if somewhat noisy BUT, I still couldnt get comfortable... I went out again this evening for an hour and no amount of fiddling made a difference, maybe I was already sore, maybe I am overtired (5hrs last night) I don't know but now I have serious doubts. I can feel a steel bar in the seat under my thigh which has been commented on, and the lack of thigh support is an omission in my book but seat comfort and refinement are something I have taken for granted and now its really unsettling me. I'm going to have to sleep on this (again!) and maybe sit in a few others at the dealership tomorrow when fresh and not sore before making a decision but this first world problem is unsettling me. Anyway, they're amazing cars, and I may pull the trigger tomorrow, so many of you love them and cant be wrong and it does suit my day to day, if not perhaps long distance cruising so who knows, we'll see. Thoughts and comments gratefully appreciated.
