How much can this smart cost?

Hello, I have been offered a Smart and wanted to ask you as a smart driver about the price. 1 hand accident-free checkbook maintained Air conditioning Tiptronic ( semi-automatic ) Central locking with remote control Pure Cdi Driving gear is in a good condition KM: 95000 Price: 4000 is this offer ok? Or should I rather put on 1000€ and get one with less km. After a test drive with a CDI from the Smart Center I was very averse because the engine was even and the car switched only at half-gas. Then I drove this and he drove much better and quickly reached the 100km/h. The car is thought to be the second car, only for city and completion drives or to eat KM. Thanks in advance.
