Could we please evaluate this mod from http://www.drivingitalia.net/index.html
it is called AC Legends Pack 8 cars 1.10.2 sound fix.
The 69 Corvette sounds and physics are just brilliant. The sound on Shelby Daytona Coupe has some problems but the rest of the cars are good. I used Zolder 67 as my test track but any flowing track would do. This mod has had 4500 downloads in 20 days, can't be too bad.
I think you will find this a nice xmas present Bruce. They also have other mods available including a Trans AM group of cars which I also like.
