I'm pretty much in the same position, although I didn't write off my 2002 Civic. It was getting old though. (Bit like me). The car seemed pretty much indestructible, and I agreed with Clarksons quip "If Honda made people, no-one would ever die".
Another Honda seemed to be the only brand I'd seriously consider, and since my commuting patterns have changed from 20 miles each way mostly on Motorway, to 6 miles in stop/go urban nightmare traffic, the Jazz (an automatic) seemed the logical choice.
Not picked it up yet, but the test drive was a pleasure, and also a demonstration of how much cars have progressed in the last 10 years.
