Good evening, I need your help. I bought a Smart 450 first registration 2005 on Monday. I bought this one from a dealer. However, this one sold the Smart in the customer order. Now I have found several defects. The Smart is probably leaking, because the footroom on the passenger side is wet. Since the battery was changed from the workshop, the workshop manager explained with the workshop manager that it has already noticed during the service. For 2 days now the Smart is jerking when starting up and the engine control light lights throughout. I know that there is no guarantee at the private sale. The dealer or also previous owner does not want to improve of course. However, in the contract is a reference to a property defect liability of 1 year (see picture). Now I need your help. How much you this: is a repair or return according to the contract right? Thank you?
