Since I got so much useful info from the forum thought I’d give my experience for any people looking buying a Model S I do quite a bit of mileage, (regular 200 mile trip to Newcastle) so the whole 75D vs 100D was a big consideration for me. 200 mile journeys in a 75D have not been an issue at all, leaving home with 95% I would get to my destination with 20% remaining. The bit of advice I picked up from the forum was to start off on any long journeys 5mph less than you would normally drive and then crank up the speed toward the end of the journey if you have a comfortable buffer. This has been good advice and I have easily beaten the estimate given by the satnav. I will point out that this has all been in dry summer weather and will have to see how I get on in winter. So far I’m glad with my £££ saving over 100D... Build quality is very good, no panel gaps etc, so no complaints here coming from a Porsche. Only slight comment would be a bit of wind noise from driver’s window over 70 mph. Standard (non synthetic leather) seats are very good and really comfortable (prob not so relevant now PUP is standard) Ok so not all plain sailing, some issues I’ve had for info: After a week of ownership we found water was dripping into the passenger footwell. This turned out to be a kink in the a/c hose. SC fixed it within 30 mins, but an inconvenience having to take an afternoon off work to get it fixed. Had an “air suspension needs service” message come up on the screen after one week. Could not adjust suspension from standard setting. Left the car overnight and it disappeared, after speaking to SC they tell me this is software glitch to be fixed in next update. Overall really pleased with the car and the way it drives. I have not experienced any range anxiety (thought I would) and would recommend a 75D for any of those thinking of taking the plunge.
