Hi! So, although I'm fairly new, I'm gonna go out on a limb and say that most providers are looking for a longer repair time in the shop than 20-30 minutes. Sure there are places that offer the Jiffy Lube experience but most of us, the quality providers are looking for, well, quality over quantity. I for one, while not a traditional Greek specialist, (I don't offer it at all) love when someone knows what they're doing when it comes to quality rim jobs. However, it's not really worth my time for 20-30 minutes. Much better when part of a package deal that includes a few hours of labor in the shop. A well-rounded mechanic taking his time under the chassis and paying careful attention to all the moving parts is really what I enjoy. Good luck though and have a great day! - London Paige
