We have 2 EVs. Air first, Polestar2 is 2nd, we often just Lvl-2 charging on Air, Lvl-1 charging oj Polestar 2, if Air doesn’t need to be charged, Polestar 2 gets lvl-2. I think 1 charger is enough for 2 cars.
Never paid for it. I suppose it’s like Private Mortgage Insurance (PMI), if you can afford to take risk, don’t need it.
It is necessary. I never done it before, but my brother did it to both his Tesla and advised me to do the same. I plan to keep Air for a very long time, therefore I did it to keep it always looking new.
I don’t think paint protection should cost more than 6% of vehicle, since it is expensive product, only does it on exotic cars.
Good questions.
