Don´t know if he´s a BB member.
You´re right, right side doesn´t look too bad.
But: Rear left is quite damaged, and the whole left (from rear to front...) side too... Just couldn´t take a pic from the other side.
I dont´t think that a rebuild of the chassis would be cost-effective.
The mentioned and pictured car belonged to me until June and now belongs to a good friend of mine.... fortunately he and another friend were not injured at all. As he told me, the rear end got loose on the wet road, he corrected, hit dry road again half sideways and just shot off into the weeds. The car came to a stop upright on the driver side after rolling. It is beyond me why the rescue people (Local fire department) cut the roof open instead of just putting it back on its wheels and opening the door? This car was my pride and joy for a few years and my heart almost stopped when I heard of this and saw the pictures... but in the end it is just a car that can and will ultimately be replaced. To me, it is much more important that I didn't lose 2 good friends in an accident that could potentially have killed them.
By the looks of things at the moment, the car will not be rebuilt. It is more likely that the drivetrain and suspension will be installed in another chassis.
Wow.... just shows the importance of a roll cage, not only for the occupants, but also for the car. I've seen plenty of 105s written off because the structure collapsed from not having a cage, and others rolled into a ball that are rebuildable because the cage kept the structure together - but it does have to be a very tight well fitting cage. Lucky people!
