Hi, i have just ordered a vito 116 dueliner (facelift model) but couldn't order the 17inch alloys as a factory option. The dealer says its because of a type approval problem. You can have them on the van & traveliner but not the dueliner. They have given me a price to fit them as a dealer fit option (£1200+vat). Does any one know what his would do on insurance if the vehicle hasn't got type approval for them? Dealer tells me that Mercedes has put in for type approval but it hasn't been granted yet.
