Thread bump!
Last year I attended the final race of the Uruguayan circuit racing championship (
photos and videos).
Next weekend it's round 2, I plan to attend.
The old Turismo Libre class has been replaced by Superturismo Clase 2, which are barely less expensive than the main Superturismo. The formula classes have collapsed, although the Uruguayan Formula 4 is scheduled for next weekend. There's also a Turismo Histórico for 1970s and 1980s cars, but they race seldomly as well.
The Autódromo V?*ctor Borrat Fabini de El Pinar has been extended to almost 3500 meters.
