What should I do to prepare my car for winter storage?

I recently purchased a 1986 Mercedes Benz SL 300 (R107) and I'm about to lay it up for the winter in a garage. Would you recommend adding a fuel stabiliser to the petrol in the tank and, if so, which brand would you recommend? Also, should I periodically start the car and bring the engine up to running temperature? Any other tips would be very much appreciated as I have been reading conflicting advice.

Try to use it as much as you can in November and December. Unless you've opted for a six-months of road tax, the main reason to lay up a car up over winter is to avoid the salt on the road - and as we don't normally see the gritters out until January and February, you've still got some crisp days to enjoy the car on. Keeping it moving will prevent flat spots forming in the rubber. If you're dead set on storage - make sure all your fluid levels are topped up. We'd also recommend investing in a trickle charger to keep your battery in good health. And yes, we'd suggest using an additive in the fuel tank. Millers make a range of suitable additives and we've used them before.
