if you can also do storage facilty that makes a bit of money there is also a place near here whop has a unit a barn and a outside yard and its always full the unit holds about 15 cars the barn about 30 cars and the outside yard which mainly has caravans and wreckers in is massive. but the cars that are kept inside are like restored and old cars and most of them have also a on site valeter who cleans the car every 4 weeks. just a idea. ive been thinking about this idea for a while with storage.
