Thanks for all the info Rafael23cc! Especially the blade lengths.
The trunk of my car isn't tiny, but the opening is. That's my biggest concern. I can fit myself in the trunk and still have room and I'm 6'2" 200lbs. It's actually quite spacious, but as I said the opening isn't. I'll probably get the TREX for now and stick a liquid on my list for next year (or less, depending on how it's working out

) I was also thinking about getting a small truck for the winter months, so it shouldn't be a problem for too long.
I assume I'd be better off with an AMA membership, as it's required for every club listed on the site you linked. Are you also a member? It's $58 to sign up form what I see, but I can't seem to find what the renewal fees and such are. (I take it they are basically the same as the current sign up fee?) How often do you have to renew?
As far as tools, I assume a nice set of basic tools (pliers, snips, crimps, ties, etc.), some small screwdrivers for those extra tiny screws, soldering equipment(?) and spare parts? My basic geek tools should do.
