If the manufacturer doesn't even OFFER one for that car, I would hesitate.
Once the manufacturer makes one, the other guys develop off of that, so it is easier to install and more likely not to interfere with things.

Just run out, start the car, run back in, finish getting ready, then go out and leave.

How long does it take for the engine to warm up and give you heat in the cabin? Dad's Jeep has heat in about three minutes but my Honda takes 8 minutes to throw off any heat. I've been known to run out in slippers to start my Honda.
