Recommissioning your car after a two-year lay-up shouldn’t be too difficult - you’ll need a fresh battery and some fuel, and we’d advise cranking the engine with a coil detached to prime it with oil before starting. Once that’s done, you’ll need to carefully inspect the brakes and clean them up, and get the car inspected by an MoT garage to check for deterioration elsewhere. You’re also likely to need new tyres and wiper blades.
