It's a bad idea to drive the car weekly during storage, it's better to prep and park it for the entire winter.
90% of engine wear happens in the first few minutes when the engine is cold and when you idle the engine it takes 2-3x longer than normal to get up to temp, making the wear even worse. This is why the manual tells you start the car and drive moderately for the first few minutes to get the car up to temp ASAP.
I store my M3 for 5 months with the following prep:
1) change oil
2) wash/wax the car
3) fill fuel tank to the top - you want no oxygen in the tank since that makes the gas go stale.
4) I drop in a can of Sta-Bil fuel stabilizer.
5) I pump up the tires to max (50psi) and park on 2x12 boards (tire cradles are even better for preventing flat spots) or even better is to put the car on jackstands
6) I hookup a CTEK battery tender. You can also unhook the battery.
7) stuff rags into the tailpipes to keep rodents out
8) install a car cover
Here is a big thread on storage with even more ideas.
