The car is ready to drive and is in its original condition with 117000 km. In addition, the price sounds interesting to me. However, the owner is not a hobbyist, that is, he only had to do the most necessary things. My main concern is the engine, because I can hardly estimate the quality inside. I unfortunately do not have tools or access to a workshop. So you would always have to let an expert in it. Can someone give me a tip which procedure is the most meaningful with regard to the engine. Possibility 1: Have an oil change at a flat rate and hope that the engine will run as long as possible. or possibility 2: …would you recommend an oil analysis. Have found the page www.oiltest24.de. There, I would be very happy to have the actual condition of the engine determined on the basis of an analysis. Has anyone already had experience with such an analysis? Is the result so meaningful to determine whether any component in the engine has to be renewed?
