The T1 was produced in Germany until 1967, however, the T1 still was made in Brazil until 1975, when it was modified with a 1968-79 T2-style front end and big 1972-vintage taillights into the so-called "T1.5" and produced until 1996. The Brazilian T1s were not identical to the last German models (the T1.5 was locally produced in Brazil using the 1950s and 1960s-era stamping dies to cut down on retooling, alongside the Beetle/Fusca where the pre-1965 body style was retained), though they sported some characteristic features of the T1a, such as the cargo doors and 5-stud (205 mm bolt circle) rims. Brazil production air-cooled vehicles (including the VW Brasilia) are a rare find in the USA and usually sought after by collectors.
