Trust me thats a lot of mileage to me I drive a Glanza with a power fc and 540 cc injectors every day with a dodgy coolant temperature sender you can imagine how much fuel it dumps every time you turn the key and the Passat needs a service so I might get more the next fill and it wasnt exactly empty nearly a quarter tank left dont like driving cars till there empty drags the shit into the fuel pump
Ive 2seats ins my GT and my daily runner is a VW Caddy. I know your not aftr a van but shes spot on, reliable and good fuel economy. Get about 500-550 miles from my tank. Had 2 306 Dturbos and they served their purpose well also!
