Really.

I would try any of the several speedway fan groups on social media eg Facebook, as that is more suited to the older fans....!

Using an inflation calculation re buying power that £4k would be approx £68k today

Why would you want to get rid one of him, good rider and one of the nicest guys in the sport.

No. And he clearly no longer wants any involvement.    It’s a sale, or no speedway. 

Also, would anyone who has worked hard to build a business over many years, be comfortable at handing the keys over and risk that business's reputation and value becoming damaged, without needing to have a very active continuing personal involvement?
