Car wash price and quality

[Gregjam]

I have not seen or can find any topic on local car wash establishments however I am sure the admins will move this if required.
When the wife insists on the car being cleaned and I cannot be bothered to do it myself I am hesitant to use the local places as I do not know how good they are and they never have prices up.
I know there are many around even on the main routes I use including the one at MV (suspect it is expensive due to location), the one just up from Big C, on 112 near the floating market turn etc.
I hate paying a farang price so will avoid any that have double pricing so can those who use the various car wash places give recommendations, prices and locations please.
The what3words app is best for location as it takes you straight to the door if you are familiar with it.
Thanks in advance.

The one at MV is of good quality and not so expensive (about 400 thb)

Really? When I asked a few years ago, I was quoted 860฿. So they obviously have a dual or opportunist charging policy. They didn't get my business.

It was some months ago. A small rented car. Maybe different price for different size ? And it was my thai wife who drive and talk...
