The new Class A sounds like how I build most of my Proxy cars! Find crappy Scalextric body, fit 3D chassis and away we go! Probably why you find my cars near the bottom of the pile.  

I had noticed that your Aston Martin DB9 did run faster this time at Harlequin in the American Road race due to the "upgrades"  you made..........unfortunately every one else had also made improvements otherwise  you might have made it to the top 
But with a new chassis and motor, who knows how you might do
