Alright, sorry,1 I thought 1/24 scale cars would be bigger than 1/25 cars. Whatever scale they are, the Coronet, GTX, Charger are made by R/M who made the Cuda in the same scale, and are the bigger ones. As for the 1/25, or 1/24, or whatever the smaller one is, I would use the one that is in the 71 Charger Street Machine version (Orange "Super Bee"). It was a new tool and very detailed.
Sorry for the confusion.
Darin, I agree with the sound of the V10. Have you heard that red/orange one? I saw it going down Brice road at Mopar Nationals and it sounded like a muscular Indy car (deeper sounding) as it spun the tires down the road and up the bridge over I-70. It converted me.
