I do not see the showroom thing as the prime reason for not selling the Fiat cars. As per my observation, it is about the end product. See people with tight budget are buying Maruti / Hyundai cars whereas with flexible budget are buying premium cars like VW, Skoda etc. Fiat cars are not cheap as Maruti / Hyundai nor premium as VW / Skoda/Honda (For Petrols). They are in between but product quality does not support premium price. Even if they are giving good discounts, still they are unable to sell cars in good numbers (In Aug some 954 Puntos and 113 Lineas were sold).
Their petrol cars are pathetic or not as good as Hondas or any other brand (Personal opinion). Their Diesel engine is a gem and available with different cars in large numbers. So no exclusivity on any front. THEY HAVE TO REVIVE THE BRAND BY CORRECTING PRICES AND REVIVING MODELS.
Else they will be history. Opening up Fiat cafe's would help but how much only time will tell. Their image is in a bad shape so even if they open a cafe in CP (Connaught Place, Delhi) I would not go from my place to see that cafe for the sake of seeing their cafe - period.
