===========================
I admit freely to being somewhat amused by how many posts we get like the OPs here on TMC (and I am sure elsewhere). I am talking about in general, not specifically, how many posts seem to be coming from a place that some regular car function (like washing it) is somehow different on this car vs basically every other car.
The answer to "how do I wash this car?" is "the same way you washed (or didnt) every other car you owned". The answer to "do I wrap and ppf this car?" is "if you wrapped / PPFed your other cars, do that to this one, if you didnt, dont".
Here is where I would normally say a model 3 is not an appreciating asset, but the bonkers car market means that at least in the short term some models of 3 and Y have gained a small amount of value in the short term, but that doesnt change the fact that this is a regular car in almost all respects except for the fact that it doesnt run on gas / petrol.
So, my question to the OP would be, what did you do with your previous cars as it pertains to washing them? I just went almost a whole year without washing my car, because Im lazy, and was working from home so was not getting it washed by the mobile service that comes to my job.
Since I am back driving into the office now (at least part of the time), I decided to get it detailed by them, because it had not been washed for over a year, and it looks fine. The point is, its a regular car, so "do what you did for your other cars", whether that is washed twice a week with a two bucket process and lovingly detailed once every 3 weeks, or not washed for several months at a time.
