I have been in RPM customer for about 10 years. There's so much good to say about RPM and nothing bad to say. They're honest, they do incredible work, everyone is so friendly and they guarantee their work, and they mean it. My sister had something wrong with your car and they gave an estimate of about $300 to fix it. When she came back to get her car she owed nothing because they had installed apart previously that failed. Also their Diamond rated for a reason.
