I have had my +4 since April 2008 (chassis number K613).
Except that I had to change the front shock absorbers for AVOs the first summer, and the brake pads the next (due to poor friction), and the walnut dashboard developing a small crack (replaced under warranty), I have had very few problems.
I have the standard water ingress into the cockpit. On a couple of occations this has caused strange electric problems, which have disappeared once the car got dry.
My only other problem has been side screen brackets rattling loose after a long trip on bad road surfaces. This was easily fixed with a screw driver.
I am satisfied with the build quality but agree that come components (e.g., brake pads and dampers) could have been better.
