Hi Mate,
Commiserations about the situation: I 100% wouldn't keep summat that I was worried about. I couldn't help but spoil every trip with fretting, wish I wasn't that way but with a motor like yours I would be even worse!
Idea. Print a letter and push it through the letterboxes of neighbours around you. I know you said you had only a couple of immediate neighbours but maybe others a couple of streets away would LOVE to have a car on their drive for a few quid a month! (Not the S8 but what about your track car??).
When we moved into our house near Barnsley FC's ground (Oakwell) there were very few parking issues on the drop curb in front of my long-ish drive.
Until Tuesday 11th of March 2014 when Leicester brought a million fans who found they couldn't park! A quick thinking German Car Owner (sorry, BMW) drove past, saw us coming home and gave me £20 to park on my drive!
To that guy seeing his team and looking after his car was worth £20. That is clear thinking. Money is there to buy you what you want; that is what he wanted.
I sold 'cos I wanted £20 more than the ability to move out of my drive with a car for 3 hours. Oh, and I was running an ancient Rover 620 at the time so wanted to show off to my neighbours! (Being Barnsley they weren't fooled...).
So. How much is having more room to park your car worth? Apologies if you've thought of this or tried already but so many of us won't ASK and then PAY for what we want...
Robert
