When I bought my S3 back in 2012 I sealed my garage walls and floor with a garage paint. I then changed the up and over door for an electric roller door that is probably the best seal you will get from a garage door.
Finally I put an Air Chamber into the garage and a dehumidifier. I have to say I had no problems with starting and the air chamber doubled up as a car cover as it kept dust etc...off the car.
I now have a new Aero 8 on order and I'm just in the process of doing the same to my new garage (3 bay garage - open inside). Just sealed the floor and walls and 3 new roller doors on order. I will be putting a wall mounted dehumidifier into this garage that will have the exit pipe run into the drainage. Should have a nice environment then to store three nice cars :-)
Fully recommend the Air Chamber/ Car o Port and Ruby Dry dehumidifiers. Worth also investing in a Relative Humidity monitor for the garage wall as the dehumidifier does not really need to be on when RH% is around 50% or less.
