Prepare your classic car for Drive It Day Classic car owners planning to put their cherished vehicles on the road for the first time this year on Drive It Day, April 21, will find invaluable advice in a Spring Start-up Guide which is free to download. Cars can often be cantankerous after a long winter lay-up and all sorts of niggles can come to light. The guide, from Mike Williams Restorations aims to help owners avoid the most common ailments in a simple step-by-step format. The guide takes owners through everything that should be done before the engine is even started, including battery, cooling system, brake and carburettor checks, followed by essential warm-up tests and advice before embarking on a test run. Mike Williams said: "April 21st promises to be great fun for thousands of classic car owners across the UK as they take to the roads for Drive It Day. However, it could become a day to remember for all the wrong reasons if the car hasn't been carefully woken from its winter 'hibernation'. Organised by the Federation of British Historic Vehicle Clubs (FBHVC), Drive It Day encourages all owners of historic vehicles, no matter how many wheels they have, to get out and celebrate the UK's transport heritage while demonstrating how many interesting machines are still on the road. In support of Drive it Day, the Heritage Motor Centre at Gaydon in the Midlands will offer a special admission price of £5 for those arriving in historic vehicles.
