Could be 200k SEK or 200k DKK which would be a believable price for a used car.
I just bought a Mercedes Maybach GLS for 270k EUR.
And why are you showing up with a bag of cash?
The other option when buying cars from Germany is to wait for the seller to receive your transfer, which could take a while if the seller is with a shitty bank.
This leaves the seller with both your money and your car.
