All,
I've owned a fairly stock 3L Milano (75) and now a SZ. Its amazing what all the small changes (shortened chassis, cambered deDion, wider track, coilovers in front) add up to in terms of handling, speed etc.
The SZ is incredible fun in the dry - I haven't ventured out nearly as much in the rain, and right now its -4 in Canada with a whole ton of snow
Regards,
