i've just started using Carcoon, so too early to comment on performance.
the zip is close to ground though - strong running water and any puddles may penetrate 'coon.
Anybody used a Permabag ?
my suggestion (ready to be shot down...): roll tyres & press pedals every week, put fan heater under car weekly for few minutes dry-off, start her up for over 30mins every 5 weeks.
