Vantage GT3 no 3D model yet one day if possible yes. The other GT3 which I will convert from FM4 are SLS, MP4-12C and 911 Cup 2011 (ALMS GTC model without front bumper led).
Still from FM4 the Oreca FLM09 will be converted one day too.
And still planned the FM3 GT1 (Aston Martin DBR9, Corvette C6R, Dodge Viper GTS-R, Ferrari F550 and Saleen S7-R)

But before need finish updating GT2 and Super GT. Painting take more time than converting...
