I took my brother in law to pick up his new Tesla on Christmas Eve... P90D in white, black interior, dark grey 21's, all extras except for the premium sound system.
Picked it up, dropped my car back at home, then drove back to his place.... 125 miles, a mix of motorway and country roads.
The obvious bit 1st... It really is hilariously fast... the acceleration from standstill is, as the mode suggests, insane. Slams you back in the seat with just a tiny bit of wheelspin from the rear tyres... the roads were very wet, and the rears momentarily spun when stamping on the throttle at 20mph. It's the fastest accelerating road car to 100ish I've ever been in. Has the potential to get a bit quicker too as Tesla are adding a 'launch mode' via software update in the near future.
From the passenger seat, it feels a lot like a Panamera... big, wide, quite heavy, reasonably compliant, but with an underlying solidity to the suspension. Very little roll, with strong turn in and grip (relative to the poor road conditions).
I like the interior. It's nothing like as luxurious as a S Class or 7 Series, particularly in the back, but the design does feel in keeping with the car. It feels quite 'techy'; the materials are decent, but the design is minimal, with the MASSIVE screen dominating the dash. His car has the 2nd gen seats, which are comfy and supportive, but soft and squishy they aren't, so you sit on them, rather than in them.
With regards to price... the list on this car was c.£112k, with a £5k government refund off that... so expensive compared to other cars of its size. But for my BIL (and his business partner - they bought 2) they make great sense when bought through their company as they get full Corporation tax write down in year 1 and there's no company car tax (which would be c.£1k/month on a £100k petrol/diesel).
