Normally, I would never go to a dealership for anything, but I needed a duplicate key for my Honda as it has a chip in it and required special programming. While there, I noticed that they do auto detailing. I had just bought a used Honda from a private sale, and it was filthy. I'm talking tan interior that was stained gray from years of smoking, sticky residues in all the compartments, stale smell from years of smoking weed in the car (there were weed bits all through the carpet). The engine bay had so much dirt on it that the car smelled like it was burning after even short drive. The car had not been loved. I felt like I needed biohazard wear just to sit in the seat.
For 125 bucks Honda West did a complete interior, exterior and engine bay cleaning. It came back sparkling, and smelled good without a residual chemical smell. It looked like a whole new car. They even managed to get out some of the exterior scratches. Definitely the best 125 bucks I've spent in awhile. My only complaint is that it was still soaking when I picked it up and I ended up with a wet bum on the drive home.
