Dunno how much design input in Pegaso\ufffd the Spanish arm had then -?- but I see the implications.
I admit to a prejudice re 'Hispanic' imaginitive abilities (contrary to the rep), based on several hearsay events and my direct experience south of this border. Which I project upon the Mother culture, in my imagination.
That is, when my SO turned an earlier Saab 99 into a bank, to evade an oncoming pindaho cabron -- they managed to straighten that space frame such that 80 mph hands-off was fine. And given that I left out the 'cosmetic body work' part, to be attended later: what they accomplished was - getting the frame/steering within specs despite some still crumpled pieces. Also fabricated a throttle control part to near-perfect dimesions .. from a fuzzy photo. (It was lost in the crunch).
This meant that they Understood what was vital and fdeduced how to compensate for what was still bent - not an obvious equation, nor one soluble by a newbie 'mechanic'.
Altogether - a level of engineering I'd not expect (then) in a US shop, where they'd just order new parts and Lots of them - as was not an option N. of Mexico City.
Guess we'll never know, given the multinational swap meet which has doomed all home growns except for exotics. Homogenized City. (I think it might be fun to do a kit car, were I in the market for more than my present quite adequate wheels. Unlikely, that. Done my share of trajectories and survived. Don't need to do it again. :-)
