Touch of ASBO about you Sirs?!

7th March 2019

An Exhaust system on a road car is inevitably, always a compromise.  The restrictions of comfort and legislation tend to make for a slightly different design than if you were building one for out and out performance.  Indeed these days, even with motorsport, an exhaust has to conform to…

Pre-War English Talbot Le Mans

11th November 2018

‘Cars that you can Google’  seems to be a term I used a few times this year.  The owners of this lovely beast would rather remain anonymous, but I can tell you a little bit about the car…

Suffolk’s Infamous Cat

30th March 2018

I’m certain I’m not alone in having ‘Pedestal’ cars that live, only in my dream garage.  For my personal taste, this includes various, mostly classic exotica; SL190, DB3, XJ220, XKSS and of course the Jaguar C Type.  (I likes my classic Jags me)  So it has been a pleasure…

Tractor Boys

18th March 2018

I’ve always liked the fact that Aston Martin was owned by legendary Tractor manufacturer David Brown.  I remember fondly the white and Orange Tractors from my Youth, and indeed my father to this day has a forklift powered by none other than an ancient David Brown diesel engine.  The…
