Question , I am able to parkour Mustang through the winter months in a dry and heated garage. Is there anything I should do since it may be parked for several months and probably not driven any unless weather is dry?

2006 Mustang V6 Convertible.

 

You will need to start it once every two weeks to keep the battery conditioned or buy a device that will keep it charged. Also, you need to watch tires so they won't have a flat spot.

 

Change the oil & filter. (removes water& acids)
Wash and Wax exterior.
Fill the gas tank and add a fuel stabilizer.(prevents condensation)
Air up the tires to 45-50 psi.( minimizes flatspotting)
Hook up a battery tender.

I disagree with starting the car, unless you can run it long enough for the oil to come up to temp, all you do is add condensation (water) back into the oil that you just changed. The conventional wisdom states that the majority of engine wear occurs at cold start, so since you`re not going anywhere, what`s the point of firing it up? JMO
