For the price it is hard to beat a Freddy's Special car wash and interior cleaning. For $25 I don't expect a full detail, and I'm generally very happy with the results. I will usually walk around my car with the worker and point out any spots they missed, same with the interior. Never once have they refused to touch up any missed spots. I've had a few of the ala carte services done as well - carpet shampoo, exterior wax - and they do a decent job for the price.
Couple of tips: there is almost always a coupon on Yelp for checking-in. Also, if you find a really good employee, ask them for a business card and call ahead to see if they are working. I've used a couple of the same car washers multiple times and they definitely give me extra service and get an extra tip.
Some of the reviewers complained about long waits. It's true on a Saturday afternoon you will wait for a bit - even an hour or so. But stop by in the morning on a weekday and you'll be in and out quickly.
Lastly, if you just are not happy let them know. I've had them start over completely to make sure the car looks right.
Freddy's isn't perfect but they are best full service car wash in town.
