There are a number of opinions about long term storage and more precisely what constitutes long term strorage. Without a doubt DeLoreans that have sat for years suffer expensive fuel system problems but storing the car for 6 months or less shouldn't be a problem. There have been a variety of opinions about how the cars should be stored and here's what I've experianced. I've owned my car for over 21 years and live in Minnesota where winter storage is a given for a car like the DeLorean. I fill the tank with non-ethonal gas, ad a can of Sea Foam, ( a fuel system cleaner which also prevents gasoline break down over a long period. Stabile is another similar product ) pump the tires to about 60psi, park the car on a sheet of plastic to prevent moisture build up under the car, and disconnect the battery. I don't start the car over the winter. Periodic starting and idling will not get the combustion by products like sufuric acid and H2O out the engine and exhaust system. It takes a good 10 to 20 mile drive to do this. When you start the car and idle it for a period of time you allow these by products to build up in the oil pan and exhaust system. Then while the car sits for another month these corrosive by products are working on bearing surfaces and muffler insides. In the 21 years I've been driving this car I've had no problems related to storage and it remains a very reliable vehicle. I've criss crossed the country many times with it and wouldn't hesitate leaving today on a trip of any length. The thing here is that the car is driven frequently with enough miles to keep things working during the summer months. Bruce Benson
