In my experience, I get an average wash, but the inside of my car seems to always be done quickly and partially wiped. I understand it's not a detailing, but it looks half done.
The staff is friendly. I don't care for the pushiness when offering upgrade washes or detailing when I pull up, but I just say no thanku, I'm not interested and walk away...then they stop. I understand it's their job to ask, so I'm not bothered too much by it. I will continue to use them when I don't feel like washing my car myself, but will try to go during the week when they have specials.
