I too jam looking forward to the Ford Transit. It will offer an I5 diesel, according to the Ford website. I think the Ford and the Fiat will shake things up. That is good.
I have a tough time thinking that the Fiat will be anything better than the other front wheel drive units that have hit the market.
IMHO, Europe and Japan have spent decades trying to get Americans to buy small engines. We just will not do it. So, don't fall into the squirrel under the hood trap and by a unit with adequate power. If you settle for under-powered junk, that is all you will be able to get. Stick to your guns a d demand adequate power.
