WOW! Really crisp throttle response and a massive surge of pure power when overtaking. Felt like the engine had been remapped and no one told me!"

All deliveries sent with DHL are supplied on a signature required service. If you have asked for the parcel to left in a safe place, we will convey this instruction to the courier but cannot guarantee this will be done as the service is a POD service and items left without signature are at the discretion of the driver.
