"I've been by Benchmark twice for different stereo work on my Jetta. Let me just say that don't be put off by the Ferrari in the showroom or the pictures on the website that shows AMG cars, etc out front. They will work on your Kia if you want them to. Their rates are actually market-price and very reasonable. They will take extra time to do things right and incorporate them into your factory mounting locations so as to not disrupt your car. They won't drill holes into your car or modify it in any way you'd be embarrassed." Bob W.
