I`d keep them seperate the torquise dont look too bad from here 
Hl.Please keep the four door,you can maybe preserve it as it is.Just keep it exspecially because of the history.Cheers GeorgeHow's that for a title? So...here's my saga. My great aunt purchased a '57 4-door 210 sedan...V8, 3-speed tropical turquoise & white. I'm told it was in great shape...then it was passed on a few times. By the time I received it, the ol' car had seen better days. When I was 10, I started putting it back together but of lacked $$$ for any real repairs. Items like the Nash Rambler rocker panels helped to disguise some of the rust. However, it was presentable...and I drove the car until I was 23. It then was passed on to my brother...who continued to terrorize it.
Now, here we are, ten years later. I've been wanting to restore it for some time, but the rust, etc., has pretty much won the battle. So, instead of doing something, I've become 'that guy' who refuses to sell the car, but won't do anything to/with/about it.
However, I found recently found a 2-door 210 hardtop. This car is fairly solid, less the normal rust (rocker panels, tailpan of trunk, corners of floorpan). So, I dragged the sad ol' car home two weeks back. Easy enough...we'll just 'merge' the two cars, right? Well, here goes. I've now cleaned it up to see what kind of mess I've gotten myself into. Overall, it's better than expected, but certainly not good.
So, I thought I'd follow suit and attempt to document the restoration / build. As for plans, the general intention is to conclude with a car which can be driven daily (LS motor, 6-speed, updated suspension, comfortable seats, etc.). However, we'll see how things progress.
