Jaguar 1999 xj8
Seven months isn't a terribly long time. Check all the fluids then I'd put in a new battery and fire it up. Fill up with premium gasoline and add a bottle of Drygas to the tank just in case you have any water condensation in there. I'd do an oil change once you get back from the gas station with the engine fully warmed up. HTH. -Jim
JS had good answers. I have had some of my collection sit for a year and all I did was remove plugs, spin engine over a bit and then put the plugs back in and start it. I did keep battery tenders on them and had Marvel Mystery Oil in the cylinders.
