Come on guys,
I don't live in the North Pole
Blankets are prone to be used on older cars but not on 2005+.
Moreover, blanket might cause the termostat malfunction leading to the engine overheat (after a fair engine load).
Jeff,
Using the Webasto for a shorter time periods seem to be a good idea, I have to check its minimum. If its 5 minutes, then I'm likely to go for it.
And if you're right with the timing of CCV problem (one year), it seems to be much lesser problem than appeared.
And once this factor is covered for a a shorter intrerval, there's still some room to think about a distant start, as it only consumes more gas, more time to get warmed, more scale on cylinder walls and exhaust system and probably lambda damage (pls correct me if I'm wrong with the latter).
Steve,
apart from a termostat injure risk (which I faced when using a modern termo-isolating material under the hood on my Honda Prelude in 2003 - on warmer winter days the coolant temperature was way higher than normal), I'm too lazy to change it depending on the weather

.
I believe $50K is more than enough to expect comfort with just using a car, without such manipulations.
Thank you for the invitation, I visit LA and Frisco each day for business trips, and Calif might be the best place for a living (especially in Orange County-like areas).
All year round summer is great but it shoud be snowy in the New Year!
