Welcome to my Site. its under constuction at the moment so bare with me.


I am focusing on Performance upgrades and Audio so please feel free to call me or drop me an e-mail. I'm happy to talk cars.


I currently own a Mercedes E55 AMG 5.5V8 the beast and a Smart Roadster Brabus.


I have made some changes to both and i will be selling some of the improvements I've made to the Roadster. For example the sump gasket. Made from real Gasket sheet not the silly rubber type that never fits proberly.


I'm also in contact with a supplier of soft top covers that you can leave on while you drive.
