As we know, and as we have reiterated several times, South America often holds surprises, particularly about classic Italian cars.
The surprise of this time is a Lancia Aurelia of 1952, so a B21 probably, but certainly not: it could also be a B10, with a 1.8-liter V6 engine, but we do not have such a thorough knowledge to distinguish them at a glance. In any case the body is very similar and the finishes too.
The interior finishes of these cars were at the top of the category, while for the body a wide use of aluminum had been used (in the post-war period, in Italy aluminum was less expensive than steel). The car in question seems intact (even if dirty) and is probably parked for decades, but it seems very complete although it clearly lacks the rear and front bumpers and, the good news, is that the seller adds to the package another car to be used as a donor.
