So, I finally made a booking to the "porsche 911" at FRA, waited for the confirmation email for 48 hours and when I´ve opened my confirmation number at avis.de website it shows:
Class: Luxury VW Phaeton TDI or similar
Estimated Total (EUR) 303,77
Instead of:
Type of vehicle: Prestige & Select Series: Sports Car: Porsche 911 Coupe
Total Price (incl. VAT). 261.27 EUR
What the hell is wrong with Avis germany?
