I agree with all the above, I am an Alfisti, own a 159 and love the brand more than any other. It is probably the most beautiful car ever built (although the rear looks like the rear of a TVR Tuscan, Race series, not road car) but I still love it.
However open topped motoring in the UK in general is for people who love themselves, and pointless.
If you want to get waved at, buy a beetle (original, not current effort), it is the original happy car. I have run two of them and they always raise a smile.
