Mike,
RAM is around your corner, they are doing a good job.
the best for carwashing i found over many many years, is La Recta Carwash up in Veron(not the one at the crossing, drive thru Veron in the direction towards La Otra Banda, after you passed the 2 speedbumps at the big Fruit Stand(the best place to buy fruits, btw, so you can combine the ride) its on your left hand side, big signs "La Recta".
i wash the cars there since years, and i do most oilchanges there, they use the quality filters and have always my prefered quality oils available.
a Jeepetas and Pick Ups cost just 250.- pesos, of course their bar always has cold beers, lol.
when new at such place, make them from the beginning clear you want crystal clear cleaned windows all around, if they bring you yoiur car, you check the windows, and if not perfectly done you send them back to clean them again. you do that once and come back a week or two later, always grab the same washer again, and be assured from there on your windows and all the rest of the car will be like brand new.
or befriend the manager Alex. since years i drive in there and park my car right in front of the door where he stores the oils and filters etc, say hello, have a chat, ask about the children and He brings my car over to the washer, be assured it will come back as clean as they would have washed his own car.
as you live nearby several carwashes, pick one that suits you and use always the same one, every time again a lil tip to the guy who washed your car, always the same guy, guarantees you lifetime service at your new place.
have fun
Mike
