A network of Premium car washes... It's a bit expensive for me. For a standard car wash, the body and interior of my Pradik were charged 5300tg, which is a couple of thousand more expensive than in the city. They even washed better and cheaper in other places.
A good sink, they wash conscientiously. It's hard to say about the price, probably, you can wash yourself cheaper and faster at a self-service car wash, but I can't vouch for the result.
