It's a shame your Fox got damaged during shipping, but it does seem to happen a lot. It doesn't look like anything too serious, but your first mistake is thinking like a car owner and not a military vehicle owner! A bodyshop is not really going to want to help you, but most things on the Fox are fairly flat and simple.
You should take the damaged wings off and take them down to a few sheet metal/fabrication places. I have found the smaller backstreet companies (one man in a shed) are more willing to help more than anywhere big.
Your flat tyre issue is probably only going to be solved by replacing the inner tube, as you have had new tyres fitted the wheels should come apart easily. This is something you can attempt, but you will need strong arms, big hammers and a lot of levers. I'd suggest getting some friends round to help, they do not need to be Fox owners to help you pry the tyre off the rim.
Regarding starting the engine, with the power and ignition on, can you hear the electric fuel pump ticking? If yes, did you pull out the choke?
Finally a lot of Foxes were modified by fitting a bumper across the front of the wings, it might be worth getting someone to make one up for you?
I agree this hobby is supposed to be fun, but the fun comes from overcoming the issues and feeling proud about the problems you have solved, either trying to locate hard to find parts or making it to or from a show despite the setbacks. We always go out with thought that we might break down, and a plan for recovery, that way when everything goes well it is a win. You've bought an old vehicle, not a new BMW, when in service it would have had much more care an attention every day to keep it in working order than any civilian owners will give it, and even then it would have broken down and had issues.
