had 2 bad experiences with them:

first time I checked a car and it had various defects compared to its age. The guy there kept convincing me that the car is good and the technical inspection is wrong. Did not buy it.

later after few years, I went there again, checked a car and agreed on the cost. Paid down payment and got the papers to do the bank loan. When I got the approval (after 3 days), they told me that the car was already sold by the owner. The car stayed there for at least 4 more days. Anyhow. I got my down payment and had them pay me the technical inspection charges. never showed them my face again.
