Yep, I fit this description to a tee. (Including the unGodly part!) And I have been storing my cars like this for over 20 years. No issues. Happy cars.

 

Unfortunately yes--they use salt here by the metric ton. However, we have been lucky enough that there has been no snow/ice YET...once that happens she goes on the charge o mat with a full tank of premium topped off with stabil until that nasty salt is gone. Until then we break out the humble 'ole Jeep Grand Cherokee

 

I can't imagine that going from a heated garage into very cold air could present much of a problem. The thermal shock of throwing cold water (far denser than air) on it would be much worse, and cars get that all the time when wading freezing cold puddles in the winter and come out fine.

 

Works for me!

 

Warm air holds more moisture than colder air. When the two meet condensation occurs. The body panels on 911's have been well protected from rust and corrosion since 1978. I would be concerned about all the nooks and crannies and various connections, electrical or other.

Going from 80F to 20f once a week or so probably wouldn't ever be a problem. If you're using your car every day I would think a dehumidifier in the garage space would be a good idea.....Chris

 

Humidity would be a bigger risk than temp I guess.
I keep a de-humidifier running gently in the garage. It takes some of the moisture out but also ensures the air moves around, helping with condensation etc.
Different climate in Scotland though!!

 

Big Lou what is the size of rims on your profile Porsche pic ? Are they Oem or aftermarket ? They look custom

 

Robbie these are stock OEM 20 inch Carrera Classic wheels that came on the car

 

sadly i cannot get my click back but on the other hand i do enjoy sharing these types of posts with others.....they do get a laugh out of them...............thermal shock ??????boiler room.......heating plant....ninja pleeeezzzz

 

What's the problem with humidity? Just an honest question. Most of the US is very humid in the summer. Never heard anyone cite problems.

 

I'm in middle TN and I have a de-humidifier in my garage as well. I have a basement garage with Racedeck flooring and some time when the gutters aren't flowing like they should I get water into the garage and under the plastic floor So I got a humidifier to keep the garage nice and dry and cars smelling great. I have it set to around 60% which I found this to be around the recommended humidity level (from on-line reading) for car storage. I usually leave the cars sunroof popped or windows down when parked so the insides stay dry as well.

I invested in some great gutter cleaning tools as well so I clean them out 3-4 times a year to keep the water out of the garage.

 

As someone who has garaged our vehicles in the Great White North, drives year round, keeps a vehicle from new till they are about 10 years old with over 160,000 miles and goes in and out of heated garages several days a week, we have never had any issues.

Temperatures in the summer up to the 80's outside and in the winter regularly down to -40 (same in Celsius and Fahrenheit )
Garage tends to stay the same around 70* F year round.

 

I've heated my garages since the late '80s. Lived in the Cleveland snow belt until 2011 and never had a problem. Kept the garage in the low 60s. I do run a dehumidifier in our present home but never did before. My wife's '08 A6 and my '08 Tundra have almost no rust at all.

 

I have a separate dedicated heat pump for the garage. 70 degrees year round. Not so much for the outside temps as they never go below freezing, but it's nice to be able to work on the cars year round.

 

I live in the Midwest and have a heated garage-LOVE it.
