I only have room for our two cars, so storage is up to you, sorry. Yes I have a welder, and as long as it doesn't become a big pain in the ass, I don't mind helping (I just don't want 10 people showing up the day before needing shit welded ) A crash bar should be pretty inexpensive, I got mine for free, I have about a 6 1/2 foot piece of 4 x 2 steel tubing, a friend of mine has 2 x 3 on his, call some steel supply places, you just weld it across the drivers door so if in the unlikely event you get hit in the door, nobody comes in the car with you The only safety equipment required is a working seat belt, and a helmet, though I wear a fire jacket, neck collar, and gloves, it isn't required. You can go to www.sunshinespeedway.com and look under the rules for demo derby cars to get the low down. Because I usually use crown vics, don't worry about the part that says you have to move your gas tank, because the tank is infront of the trunk they don't mess with you. If anyone already has something other than a crown vic, it's not a big deal, you just have to mount a boat type gas tank up inside the trunk. I'm glad to see so much interest, it really is a blast. Anyone that is serious, you can bring me half the money up front so I know you're serious (sorry, I just don't want a bunch of $250 crown vics sitting around), and the other half when I get the car, which shouldn't be hard (I could have probably bought two more last night, but I didn't know so many were going to be interested) Of course if I can't get one, I'll give your money back, but I don't think it should be a problem. PM me for directions.
