In separate articles or reviews, The Wall Street Journal notes the return to the US of two classic Italian cars:  the Fiat 500 and the Alfa Giulietta.  The Fiat 500 is the iconic tiny car that defined an era for many Italians.  The new version, defined as cute but hip, performs well and has been very popular in Europe.  Whether it will sell in the US remains to be seen.  The Giulietta, sleek, sexy and efficient, is scheduled to be available in the States starting in 2014.
