Here at Autoplenum nobody sells his car.
Autoplenum is for questions about cars. To help you with your search here i give you a link with Ford S-Max Cars which can by buy.
All these cars have a diesel engine, everyone is in private hands in Germany.
7.500 Euro with 140 hp and Titanium in an S-Max is very difficult. In find 5 cars and only 1 Titanium.
If you wan't an S-Max for that money, you have to make compromises.
