Chevrolet Spark

It is not right to judge the performance of a product with respect to the dealer. This cannot decide the quality of the product. You should take it up on higher level at GM. (This needs follow up - with every company)
With regard to the quality of Chevrolet Spark, I am the proud owner of Spark. Extremely good driving comfort, styling is good. Fuel consumption avg @ 14-15 km per liter (city & highway). Quality of the interiors is good.
As regards to the brand, Chevrolet is a renowned brand & people really look at your car when you go out.
