Well, they don't look the best. They do look industrial. I suppose you could easily paint and pinstripe it though to suit your tastes. Other than that, it's a box with a door and has the same (if not better) lock than the gun safes do.
No, it won't fit in your car. Best bet is to rent a moving van with a tommy gate that has a rating suitable for that safe. So if the safe is 1900 lbs., you need a one ton tommy gate.
If you have a garage with a concrete floor, you're fine. You back up the truck to the garage, drop the gate with the safe in it, roll it into place with the small dolly you rented, then drop it on low blocks. Have friends help or get ingenious (block and tackle?) to lift or rock the safe to remove the blocks it rests on. There's a mat that you should put between the concrete and safe, regardless of what you use.
If you have a house with a concrete slab floor and want it inside, then just back up the truck and drop the gate to the front door. Lay out heavy plywood flat on the floor to make a path (I'm not sure what you are supposed to do if you have ceramic tile or wood flooring here, but this works on carpet and concrete). Basically, do as above, except here you drop it on the carpet ultimately.
In either case, you could stop by Mako or some other quick auto-body paint shop and get it shot however you like (airbrush would be cool) if you plan on displaying it or it being seen. I agree, the institutional colors they come in are boring. On the other hand, there's always covering it up somehow, just getting ingenious.
Anyway, you don't have to know much. Just be patient, look on CL in the nearest big city/county search(es) and hold out on a safe that's the right size for you (they come in ALL sizes, makes and models). You just need the model number on it (usually riveted in doorframe) to match up to the UL rating (usually riveted in same place). And you want that UL rating to be, ideally, TL15 or TL30 or better. It's pretty simple, actually.
Now if you don't have a concrete floor, things can get tricky... But if you have a stick floor house, you'll likely need to reinforce the floor for any decent gun safe anyway. So why not have a good contractor come and just reinforce it for the heavier TL30 instead?
I don't get it, I'm just trying to help you. I'm not even trying to sell you anything and I even commend you on locking up your firearms. Now I've had the other gun safes, nice shiny ones too, and nothing beats a jewelry safe, nothing. Been around the block, and I do know a bit about security. So that's why I'm saying the UL rating is key, and for price, those two ratings will be the ones you can afford if you save up and are patient and negotiate well and watch CL everyday.
But do what makes you sleep tight at night when away from home. That's what counts, right? Seriously. So good luck in your purchase, that was just my $1.02. Take it easy!
