I always recommend you carry out a staggered full 36,000-mile (60,000km) service of the whole car in between driving the car. Priorities to check and service or repair as required are brakes, steering and suspension (all three include tyres) safety electrics (lights, horn. wipers, blower, etc.) reflective number plates (see and be seen). A 12v battery in good state of charge and health is always best, also helps with diagnosis of starting, electric and electronic issues. Check all cables, wire, connections are all clean, secure and protected. Engine, gearbox (diff) - replace oils and filter(s) and as much as possible and practical clean and flush. Replace plugs and other ignition parts as required. Clean fuel system (replace filter) as possible, check fuel pump. Cooling/heating system - clean, flush, back-flush, flush again, refill engine block, radiator, pipes and matrix. Clean external rad fins and grille. Thermostat, sensors and water pump as required. Power steering - flush replace fluid. Actually frequent regular use of the car will help you to sort the car and learn how to drive it and what it is capable of, once fully(?) sorted you don't need to treat it much different to when it was used when new. Keep letting us know how things are going.
