I need to store my ’88 Mini for two or more years. I have found a lot of advice on shorter term storage, say, over a winter, but nothing for long term. I need advice! First question: for two years, is starting the car every few weeks better then preserving the car and not worrying about starting it? I can remove the gas tank and all gas (tank is rusted, so needs replacing anyway), fog the engine, and so forth. I am concerned about the gas going bad and gas odor build up (the car is definitely gassy). I also don’t want to burden someone with the chore of maintaining the battery, starting it, changing gas, etc. Preserving would also let me remove the tires to save them, as the car wouldn’t be moved. I have a metal shed I can put the car in. Currently it is not sealed up, but I am thinking of framing it out, sealing it, and insulating it. If I preserve the car I would add a dehumidifier (but not heat/ac). If I leave gas in it, I will have to ventilate the space, which means no dehumidifier and ambient air exposure and humidity concerns (it is central TX, so not horribly wet, but not arid). Other options are a car bag or one of those inflatable cocoons. The bag would need desiccant and I worry about gas fumes if gas is left in the car. I have read mixed reviews on if the bubble cocoon types. Some say they prevent moisture buildup, but others had horrible experiences. They also require filter changes and the fans may fail. I am leaning towards the preservation option with a dehumidifier. I could put a vent fan in as backup. If I go this route, what other things should I preserve and how? Anyone have experience or tips they can offer?
