There's nothing to service, so I'm not entirely sure what could be adjusted or replaced. In the vast majority of owner reviews I've read, they don't require any attention other than wiper blades, screen wash and rotating the tyres and/or eventually replacing them. Tesla do not recommend any servicing other than changing the pollen filter - which you can do yourself pretty easily.
Tesla advise that the brakes should last the lifetime of the vehicle - it's one pedal driving with energy regeneration, so the brakes are very rarely used.
It is uninvolving because there's no drama and there are no discernible characteristics. It's not like a Ferrari, a Morgan or even a BMW or Mercedes. It is an annodyne, rather clinical experience. As you suggest, it's rather well balanced, has great steering, low centre of gravity and easy to drive. I am not complaining in the slightest - I rather like it actually! Having owned everything from a vintage Le Mans Aston to a Bentley and everything in between, the Tesla is both novel and interesting. It is as exciting as having a new fridge - but there a delights in such a thing... whether that be a silent ice dispenser or low running costs.
ETA - Alistair, you are just down the road from me.... when this madness is over, come and have a drive of it.
