The 2008-2009 Jazz's were built in Japan, not Swindon. My EX now has 66,000 miles without missing a beat. Gear change is still positive, steering is still tight, the paint is good, all the electrics work well, the seats show no wear because I've had covers on them, and engine is still on song. I've been told the brake discs may need replacing soon (fairly common on modern cars with heavy mileage in all weathers), and I had all 4 alloys replaced under warranty due to corrosion at the centres.
I understand Jazz GE's are getting superb reviews in used-car surveys. I couldn't recommend one enough
