Just purchased a new to me Avalon and as I was cruising down the highway, I had significant vibration through the steering wheel and seat. Contacted Ken, who was able to get me in the next day as he thought it was just a wheel balancing. Turned out to be off a great deal and he fixed it promptly and now I have zero vibration cruising down the highway! - Dan M. (5 star review on GarageFly)
