Mention "upgrades" to a group of Classic Car enthusiasts and you'l get a diversity of opinions. There is a spectrum of opinion ranging from keeping the car exactly as it came off the assembly line to an absolutely "anything goes" attitude. My personal view is that if an upgrade makes the car safer, more durable or better to drive and if it can be converted back to factory standard, there's not much wrong with it.
I market a wide range of upgrades for both the Dart and the Saloon as you can see from the following pages:
SP250 Upgrades
Daimler V8 Saloon Upgrades
Upgrades for both models
