Not even close (beyond engine output at least). The Fiat (especially in cabrio form) is a much more entertaining and upscale package. It appeals to those with plenty of disposable incomes, to those with just enough to pop for a pop, who don't care or need the extra space available in other cars.
The Mazda 2 is something you buy if you can't afford more, or need/want the extra space.
Nice clip. What makes me like this vid is that they both 'get it' about the spirit of the 500. It makes you smile! It's not about numbers. But also fair and square to say that the two cars really are different to each other, and not necessarily aimed at the same market even though they are similar in (base) price.
Plus the 'Vespa of cars' line is nice too. At least I have that part covered. A 500 is next. Hmm, might have to be a matching red.
