Service After the Sale. For years the Klaben Family has maintained a tradition of professional sales and service before, during and after the sale. Thats why over 50% of our business is from repeat customers and their referrals. 129 Point Mechanical Inspection Every vehicle we sell must pass a 129-point inspection. No vehicle leaves out lot without new oil, oil filter, and the brakes must be at least 50% or we replace them.
