I raced my XX again for a summer season back in 2012 with brushless motor etc - what a fantastic car! I got to race it again at this year at the Iconic vintage meeting, this time with a period correct brushed motor but it was still a joy to drive.
Personally I like the 5 spoke wheels - far more interesting than the boring generic dished wheels we use these days... looks like this XX has the 'holy-grail' of XX upgrades... the Trinity front bulkhead! Just make sure you don't break your chassis instead
