I recently posted a one star review for Jackson's car wash on A Google site. I am amending that somewhat here.
It is true that they egregiously upsell. It is also true that they are generally annoying and tried to sell me things I did not need, and Told me things about the car that probably were not true.
However after all of that, with me refusing any of the things they were trying to sell, I have to say they did a remarkable job with the wax job on the Lincoln. The car was spotless, and the wax was perfect. The gentleman who actually did the work was very courteous and obviously knew what he was doing.
So if you can resist all of the BS that goes on when you deal with these people you probably will get a car wash and wax that was actually worth paying for. But like dealing with the worst of a used car dealership it's difficult to get past all of the crap on the front to get a very good job in the end.
If you asked if I would actually take another vehicle there the answer is probably no I would not! But if I could work with that guy that does the detail work I would pay him considerably more to get other cars done.
