If I remember correctly I watched that episode of top-gear were Clarksen got up to all kinds of mischief driving it hahaha

I found this very interesting...

The 1963 model retailed for £199 when new (about £1,400 in 2010, or US$2,200). The company produced 50 P50s and only 27 are known to still exist, one of which was sold for a record US$176,000 at a Sotheby's auction in March 2016.

Thanks for the post I thoroughly enjoyed it!
