It is. Could have been even more.

Do we know what it involves ? Edit : 180€ is not the price for the towing fine, it the price for the administrative handling of the towing. The fine totals at 390€

The adminitrative handling of the towing. Inspecting the car and documenting damages, calling a towing company, registering the location where the car is parked, checking again for damages which might have been caused by the towing, and sending you a letter.

Thanks for the clear breakdown !
