How much for waxing my car? And also my car has a scratch not tooo deep but visible. It is possible to erase it with just buffing the paint?

You're better off going somewhere else. They left streaks on my windows. They're always in a rush, and for the price, not worth it.

I can't remember exactly how much for the hand wax. I'm planning on having it done myself. It ranges from $50+ depending on the type of wax like "Mother's" Wax. Check out their website. I took my car to their detail center (same location). I had a few stratches on my car and they were able to buff out the light ones, however, the deep ones they could not. They are so nice, they didn't even charge me to buff the small scratch but I left a nice tip for the guy. This place is very professional and clean. I drive quite a ways just to bring my car here. You can always call them in advance to describe the scratch to them and they can let you know if they can possibly buff it for you. Hope this helps ;)
