For just $5 you can skip the interior cleaning and get a "basic" was which allows you to run through the main show. They may call it basic, but my car came out of the wash cleaner than a baby's butt.
The whole system was pretty efficient, except for the entrance for the skip-the interior-cleaning located on the far right. From entrance to exit, it took less than 5 minutes. Overall, I'm pretty satisfied and would return to try out their interior service as well.
