I like the idea and concept of this mod:
The "XJR-15" is a really nice, perhaps somewhat forgotten and under-the-radar, Jaguar model that is distinct from many other car manufacturers.
Unfortunately, most of the execution and implementation of this mod is too flawed:
The exterior is nice and accurate looking....but slightly more 'cartoonish' than are most other rfactor car mods I've ever downloaded.
Ditto with the interior, it looks a little more 'cartoonish' for lack of better adjective, but otherwise it was fairly-well detailed.
The engine sounds seem slightly weaker, more tinny, and less pronounced than do the engine sounds of other vehicle mods I have downloaded for rfactor.
The crash model also seems less complete and inferior also: Crashing these vehicles several times at high velocities didn't cause near the amount of vehicular damage that other mods have.
Finally, I VERY OFTEN had troubles with the gear box of these XJR-15 cars -which also happened to the A.I. Jaguar cars: The gears would 'get stuck' on 3rd or 4th gear very often requiring a succession of deceleration then acceleration (numerous times) to fix this. I've never encountered this dilemma in any other rfactor mod other than this one.
