Following this thread with great interest.
If you could one day create a batch tool that automagically adds IRL names to the gtdx or whatever that file is called, that would rock.
Currently have 400+ cars in approx 60 add-on packs.
Just recently got an issue that might rain on your modkit parade though:
I reserved 2222 for testing modkits (if tuning didn't work, I can check whether its the modkit number or a syntax in my carcols lines...).
When importing various cars all of a sudden 2222 stopped working on me.
I figured it was something in the carcols lines of one the most recent imported cars but no.
I rolled back my actions. And 2222 worked again on car15. Okay, import car16 with its own unique modkit number 442, still 2222 works on car15. Okay, import car 17 with modkit 443. Now 2222 stops working, no tuning on car15. Hmmm so it's in carcols lines from car17 I figured? So, I deleted all carcols lines for car16 (!!!!) and low an behold car15 with 2222 has tuning again? Dafuq...
