I'm posting this in here because Kivlov or BiGi both move the thread that I post in the mods forum way too quickly! I can't answer to the thread and explain my problem -.-
Anyway, if you read my other thread in the "old mods question archive" then the problem is explained in there, but I think people are misunderstanding the problem. The car code I posted in there works perfectly well, and all the cars show up. But when I install a new car, all the mod cars disappear, but they come back when I uninstall the car from the game (I do this by deleting the files and folders associated with the mod.)

The mod cars I already have installed are:
Range Rover 2012
Ford Fiesta
Volvo XC70
Nissan Qashqai
Smart ForTwo
Cadillac Escalade ESV
Hyundai Santa Fe
Volvo XC90 (By Daeman)
BMW 7-series 2011
Ford Focus ST 2006
Ford Focus 1.6 2006 (Add on for the Ford Focus ST)

I also have the New Summer mod, and ENB V2 mod installed.

If anyone has any clue as to how to solve the problem, I'd be most grateful.

Show your code here. I want to see it. This sounds like a code-editing error .

There's a special topic for questions regarding the mods:

I think we should stop to procreate huge numbers of similar topics. Our forum grows and requires more accurate communication and more strick rules following.
