@racer-x 1. Since when can you compare Car restoration with GTA Mods? 2. Who cares if they are your standards, maybe other people are fine with it? Maybe they like it as it is and are happy to invest some time to make it work and aren't "sh!t not working" and give half star rating because they aren't willing to put time into it and at least try to to make the mods work themselves. Your attitude would be kinda understandable, if you paid for a mod but all of this is free and people invest their free time so other people can enjoy it as well.
At some point though you reached the game's limit and neither of the parties is really the one responsible. Just my 2 cents to this. And this "take it or not go away" Motto is nothing really bad as the mod devs don't have to help you but they do as they want to get it done working for you as well, like @Cyron43 did but in the end people seem to be too stupid to understand that it may be their fault and not the mod creators.
