I've been to Delta Sonic for a couple car washes in the last two months. I'd give them three and a half stars from my experience, but my wife likes them when I'm not in the mood to wash her car and she likes them, so I'll round up to four.
So far, I've only done the Super Kiss option where I go through the automated tunnel and then they hand dry my car. I like that the process is quick, even with several cars ahead of me. I'd say the process takes maybe 10-15 minutes. I haven't used their interior cleaning service, so I can't comment on that. The drying process could be better. In both cases I've had water drip off my side mirrors even though they use an air compressor.
Prices are a little high, but I like how you can get one or two car washes for free within a certain time period, so if it rains the next day, you're covered. It looks like you can get a monthly "subscription" for car washes too, which might be good if you want to run your car through the wash several times a month, but that's not for me.
The gas prices are pretty low, with or without a car wash, so that's a plus.
