One of the mods which I have so far downloaded and 'test-driven' by "Endor Team" is a superb rfactor vehicle mod. Unfortunately, this mod by Endor is very very subpar.
The exteriors of these 1977 vehicles look great. However, from testing two vehicles, this mod seems very very buggy and poorly done. The cockpit view from one of the teams' vehicle which I tested was totally off -as though the driver was standing up: The driving physics sucked and were very poor and inaccurate.
The other teams' vehicle which I tested had a more accurate seating position in the cockpit view. However, the engine sounds were almost nonexistent and turned on and off at random. Once again, the driving physics sucked.
All files were copied from this mod to the correct rfactor directories...
