Limit: 280,00 €

And it got sold for a whopping € 650,- (excl. fee).

As can be read in the description, the washing takes place in front of the Villa of Enzo Ferrari. I'm unsure if it's Enzo's 365 GT4 2+2. If so, I would expect the license plate starting with MO. According to Wikipedia EE are temporary plates:

These plates are used for vehicles temporarily circulating in Italy, but have to be exported, "EE" stands for "Escursionisti Esteri" (Foreign Hikers or temporary plates).

Update 13-5-2018: I received some additional information:

The 365 has Italian export plates and is the German model (orange/white front reflectors, Round chrome outside mirror and probably hexagonal wheel centres rather than spinners) so I assumed it was Laudas company car.
