Actually, the rollbars and windshield are easliy fixed (they really need to be
). I have seen B&B's in wrecks before - they usually come out the winner. There is a story running around about one getting broadsided by an Expedition! Bruises, but otherwise OK.
The B&B builds are like many others - the value is in the equipment. A donor build with an everyday engine is not worth that much. A new-parts build with the right suspension, engine/drive train, brakes, etc. can be worth much more. The body has no rear flares and the narrower front, so the front wheels needs a lot of backspacing for the car to look right. The body and frame is a great platform - very little flex and very strong. The body is very thick and heavy. The options (roll bar(s) interior, windshield, etc.) are not as nice as some of the other brands.
Also, if you need to paint it, this would be a good time to cut out the big thick panels around the edges where the hood and trunk fit in.
It is a good car, but needs some extra work to make it look right. When it is done right, I think they make really nice cars.
Good luck,
Brian
