Rainbow Buick GMC
Rainbow Buick GMC in Covington LA has certainly set the bar for customer service! Never have I had such an excellent experience at a dealership as I have at this business. There are not enough words that can express my gratitude before, during , and after the sale of my GMC Sierra 1500 Denali. Everyone from the Front-desk Receptionist, Sarah McGuire, Accounting Ursi Dexter, Parts Dept. Justin Lee, Body Shop Mgr. Andy Curry, Service Manager Joel Miller and his team if highly skilled and personable staff. I can say that Owner Craig Boudreaux DEFINITELY knows his business and his team of AMAZING staff honestly cares for their customers!!!n Thank you RAINBOW NORTHSHORE BUICK GMC!!!
