For cold starting, you need to learn to work the glow-plug cycle. The glow plug light comes on when you turn the key, then goes off after a few seconds. However, the glow plugs themselves are still turned on, and will continue heating the cylinders, for up to a minute, until the glow-plug relay shuts them off. Unless the cylinders are warmed up by the glow-plugs, you'll have a very hard start in cold weather.

The secret is to let the glow plugs work. On cold days, I usually watch the glow plug light, and when it goes off, I count to 30 or so before turning the key to start. On really cold days. I'll turn the key to start the glow-cycle and then wait (maybe 45-60 seconds) until I hear the glow relay click off. Then I turn off the key and turn it back on to start the cycle again, waiting 30-45 seconds after the light goes out. On occasion, I've turned off the key and repeated the cycle a third time--but that's when it's really really cold.

Assuming your battery is good, the car should start well.

The other thing you can do is change the oil to a synthetic oil, like Mobil 1. The engine will turn over much easier with a synthetic in it.

Best of luck with the new car.
