I have been going to IMC Wheelcrafters for over 10 years, mostly to install tires. http://www.wheelcrafters.com/
Hugo and Mario does excellent work, never have any scuff marks on any of my wheels when they install those low profile tires. Mercedes Benz of Sugarland bring their customer's cars here.
