Breif update due to lock down boredom. Finally got around to fixing the handling issue, turns out it was just the tracking. Didn't realise bad tracking could have such a drastic effect on how a car handles and feels on the road. Now she sits straight and the wheel stays centred. Steering feel has been restored and I've regained my confidence back. The steering has excellent feedback, I'd forgotten how well the boxster handles.
I also fixed the roof as it was not lining up on the right side. Assumed it would be catastrophic and a specialist job, turns out it was just one of the plastic ball joints which are designed to snap under pressure so nothing more important does. The small parts came in pairs, expensive at £27, but a 5 minute job requiring no tools. Easy and cheap to fix considering.
I also made a short video on my favourite roads, enjoying the traffic free roads due to lock down. Critisize me if you will, I needed to get out the house, I did not see a single soul and didn't get out the car. I also respected the speed limit. Couple of pictures too. Enjoy and stay safe!
