Hi again, as you said 6 years, over that time what fuel that was left in the tank will have caused moisture through the fuel lines/ filter, your car if you intend to keep wants a real check over from the tyres which can crack on the walls by leaving it standing, the air filter believe it or not can get spiders and a lot of dust inside, the leads needs to be checked, it does not do to leave a car that long with the occasional run, last point, I would get the car re-tuned to finish the full & complete service.
