Here`s my 2 cents.
1. Get an oil change.
2. Fill up your tank with “SHELL 91” and add a stabilizer.
3. Pump up the tires by 10%. Store your track tires in the basement with 10% less inflation.
4. Either pull the battery and store it in a ventilated cool dry place with a towel over it to block any sunlight OR simply hook it up to a trickle charger.
5. Wash it, wax it and cover it.
6. Throw some dryer sheets in the car, under the hood and throw some mothballs under the car to thwart any unwanted friends.
7. Finally, say good night and don`t drive it till Spring. Short jaunts in winter aren`t doing your car any favours unless you really give it a good workout and then follow points 1- 6 all over again.
This process has worked for me for the last 20 years with no issues in the Spring.
If you need a Porsche fix, buy a 944 beater and have some fun with it…..Wayne
