Depends on what you want to pay. Most i have ever paid for a rear quarter panel dent has been RD3000. The nicer looking the place the more you pay. There are a few places in Cerro Alto you can go on the cheap.
well it is a pretty major dent (the front quarter panel on the passenger side is basically flattened and needs replacing), and the car isn't mine so I better fix it. Took it to the Hong Kong place on Rafael Vidal, it does look like the owner knows what he is doing, thanks SKY.
I was sent there by the service manager of Toyota some years ago. They did such a good job I became a repeat customer. Not proud of being a repeat customer, but yes, they are very professional.
