I have seen the 240 convertibles, I always thought it was some shop around here that had been making them! Like you say though, structural rigidity is not their strong suit. A million years ago my buddy bought a '69 Caddy 4 door, and proceeded to cut the roof off of it. I think it lasted 3 weeks before it had shifted and sagged so much that the doors stuck and got hard to open. And that's a '60s Caddy with a full frame. If that Prelude got a flat tire, I'd be scared to jack it up on one side just in case it bent lol. Doesn't mean I am not fighting the urge to buy it though
