My dad bought two groupons for us to use to have our cars detailed. I'm planning on trading mine in soon, so the timing was good. We set an appointment a couple months out, then we had to go out of town at the last minute, but they were happy to reschedule us for a week later with no issue. My dad's suburban was done first, and when we pulled into the parking lot he was already exclaiming about how great it looked just from the outside. I had my SUV done the next day, and let me tell you, my car was a mess! I honestly haven't deep cleaned it in the 5 years that I've owned it. It's lucky to get vacuumed once every couple months. I had cup holders used to hold change that had gotten sticky from spilled drinks. There's a well underneath the driver's seat that seems to collect everything and the vacuum has never made it back that far. The vents have never been cleaned of dust. So, I was a little nervous about what they would say about my car. When I picked it up I was told "don't worry; we've seen worse." I must say that my car hasn't looked this good since the first week I drove it off the lot! Even some of the little door ding paint smudges were buffed out by the nice wax my car received. This was a great experience and I would do it again. I think the 1-star review here is really unfair. Anyone who has used Groupon before knows that businesses get inundated with calls after the certificates are issued. If it's for a service business like this that requires appointments, you are going to have a wait - it doesn't matter what the service is. I have to say that the wait was worth it in this case. They do a great job, and they even have experience working on classic cars, so don't be hesitant to take any vehicle there.
