It sounds nice but it looks very poor graphically.
And performance wise, its maybe the worst classic Le mans car. The 2D, the Mark IV, the Ferrari, and the Jaguar can outperform the GT40. Also its free if you win the Indy 500 B-spec race.
Well it sounds awesome -I think it is a fun drive, it isn't as fast as more modern cars, so you may find it tough to use it - day to day- so to speak but youcan say the same thing about the Ferrari F1 cars.
The downside is the lack of a cockpit and Standard Quality Graphics - which are not issues if you drive Classic dials view and don't really watch replays to see the flaws but to wach the action.
A Photomode picture of a "Good move" could look less excellent when you see the car look a bit jagged in places.
I'd say get it as getting Kazula Credits is easy- but finding that GT40 will not be easy.
Free in BSpec eh... Forgot about that Good spot RP
