When it comes to supposedly low prices, some people interested in used cars turn their heads off. This is a lot of trouble.
There are seldom used car bargains. Often there is fraud behind particularly cheap offers. The Cologne Police Headquarters draws attention to this on the occasion of increasing cases. The police advise to be suspicious of supposed bargains. No seller sells his car below its value. The "bargains" are mostly stolen vehicles. The papers supplied come from break-ins in registration offices.
According to the Cologne police, the scam is always similar. A vehicle is offered on the Internet at a price that is significantly lower than that of comparable vehicles. Interested parties find out that the car is still available, but not, as stated in the advertisement, near the buyer's home, but far away. The idea behind it is simple from the point of view of the fraudsters: if you take a long journey to get there, you are less concentrated at your destination and you don't want to have made the whole way for nothing. So is more willing to make compromises.
The police warned against further action by the fraudsters. The agreed inspection of the vehicle is often delayed and finally takes place in the dark on a street. Used car buyers should be suspicious by now at the latest. An inspection should always take place during the day at the seller's place of residence. It is best to make sure that the name of the seller is on the doorbell at the address given. If meeting points and times are changed at short notice, this can indicate a scam.
It is also important to have the provider's identity card shown to you. Does the picture in the ID really match the look of the provider? ID cards obtained from pickpockets are often used for sales. You should also look carefully at the registration papers. Spelling errors in official documents indicate a forgery. The issuing authority is also already printed on the back of the registration certificate Part I (vehicle registration). If this does not match the authority on the front, it is a forgery. If you have any doubts, you can call the police to check your car. This usually ends the sales negotiations immediately.
By the way: Anyone who buys a stolen vehicle does not acquire ownership of it in accordance with Section 935 of the German Civil Code (BGB). The money and the car are gone.
