A fun & easy experience
Foundation Kia has a fantastic team! Pat helped me find the perfect Sorento & I could tell he really cared and really knew his stuff. Gary in finance got me the best financial & protection packages and explained everything. I couldn’t be happier with the whole experience! After a thorough walk through of features, the sales manager Tanner shook my hand and made sure I was happy with everything. I love my new Sorento & the team at Foundation Kia. They’ve earned a loyal customer!
