The service that I received was so good that I cannot think of a way that it could be improved. I started contact with K's Autohaus when I needed to replace one low-beam headlight. Another service company was going to charge me a very large sum for this task after a wait of about one hour.. I looked around in my area and selected K's Autohaus & 4 other services. I was passing a dealership so I offered to bring a replacement bulb. When I reached K's Autohaus, in Humble we determined that I had been given a replacement bulb that was much smaller than the one being replaced. So I walked across the street to vehicle parts supplier and bought a correct replacement. When I returned to K's Autohaus, the technician popped it back into my car and would not charge me anything at all. I wanted to avoid driving with a bad low beam so costs were of no concern to me so I was mightily grateful. A few weeks later my vehicle dad reached its service interval so naturally I returned to K's Autohaus, I had my oil changed, my tires rotated and a non-critical running light replaced in about 1 hour; for much less than the "very large sum" quoted for just the original bulb replacement. I'm avoiding absolute costs to avoid limiting future quotes. I place a large value on my wait time so I consider I've made out like a bandit on my time and the final cash cost is inconsequential. I'm a very, very happy customer.
