Buying from a dealer really can be migrane enducing, they don't tell you the real story. Luckily they were more than welcome to do the vehicle inspection before selling it to me, and it passed (with a minor problem with a light, not sure about that but we'll see).
mrbrian200, that should be 6-7 l/100km at 100km/h on a straight highway. I'll check that and report right back with results after test driving. Got a long drive soon so hopefully everything will be fine before-hand and can take the car for a real drive
Thanks for the tips everyone so far! What a good and helpful community
