Hi recently i have to use car rental services in Sofia, Bulgaria. The car that the company "SkyAuto-car rental in Sofia" here is the link : http://www.skyautobg.com/?l=english&; offered me was Opel ZAfiraent . Really fascinating car it has 6+1 seats but it is fast ans comfortable. If you ever need to use a car for the weekend I recommend you that vehicle it is great
