When I moved here from Charleston 3 years ago, I had a terrible AC problem that the Volvo dealership in Charleston had never been able to fix, althought I had paid thousands. I have heat intolerance and I cannot be driving around in a car with no AC. The Volvo dealership always tried to get me to just get a new Volvo and I so love having no payments, that was not going to happen. Well, Imports Plus is close to my house in Irmo, so I drove in there and met David (owner) for the first time and described how it would act up but I could not duplicate the problem when it was in the shop. He advised me that the next time it acted up, drive it straight to his shop and don't turn off the engine, and let him come out to the parking lot and look at it. I did. He did, and he NAILED the problem right on the money, fixed the AC for a reasonable rate, and I have been driving in air conditioned comfort ever since. This old Volvo needs to last as long as possible and I am 200% confident that it is in the hands of the most highly skilled people I could ever find to make that happen.
Pros: Ability to fix stuff that the Volvo dealership could not
Cons: None that I have ever found.
