yes! Private drivers who had wallet big enought has that possible.
Trollhattan sold those Red cars for example to Finland before Saab factory started in Finland 1969.
After that, factory team made own cars between 1970- 1977. Ewery years made 2-4 samples and after 1-2 years of use, sold them to private drivers. I don`t know if swedish team sold works cars after use to private ?
