Sorry to see it go, but appears the small city car suits you better for the OP given the "problems" with the car.
You can always count on Sarnie
Its true though.
Tax, tyres and petrol haven't really changed in price recently.
Nor has the size of the 370's petrol tank or engine.
Afraid I have to agee. The Zed is not a good town car, it will drink fuel like mad if you are constantly stop/starting it. Its desgned as a mile muncher, cruise across Europe and you'll see what its really for. We loved taking our to the South of France, it was brilliant and got about 30MPG across the whole trip. However when its at home and pottering around town the MPG is scary low. Its a big heavy car with big thirsty engine, cant expect it to be light on consumables unfortunately.
