Hey Gold,
Thanks for your reply and I appreciate the guidance! I think along with everyone elses feedback here the best course will be to avoid a cover. Have you every used or have any experience of custom covers to the vehicle or are these a 'sounds too good to be true' snake oil pitch?
My drive is also on a pretty steady slope so tent is off the cards as is a car port as I'm in a rental right now.
In terms of water ingress, I think we're all good headliner is in great shape sunroof seals look good, I did notice a wee bit of water in the drivers side door well/Sill (where the corrado branding is) so may have to replace the seals.
It's off for a health check next week, I've done just under 200 miles since I picked her up last friday and can't stop grinning with every journey I take in it! I think my major upgrades will be a Cat-back stainless exhaust from aa wizard near me in Buckinghamshire (ARO Exhausts) and I'd love to get a stock big spline wheel back in there - has a Momo one in at the moment that handles nicely but feels a it boy racery.
Thanks
