Glad you mentioned this was a crazy idea because you know I'm going to debate this topic very hard.
* I've already stated my case on No Used Cars. KEEP THE M:censored:F:censored:ING USED CARS! I'm tired of this crap. Just because you don't want them doesn't mean someone else MIGHT want them. Don't be foolish. If you take away Used Cars, it will just be GT3 all over again. Do you REALLY want that to happen? I don't think you want to... * Next point is that not every manufacturer has made 10 cars for each type of car. This goes back to the complaint about not having a car company in the game if there's only one car available. Look at Lister. What are they best known for? The Lister Storm. They also made that ugly LMP powered by a Chevy motor. So what if only one car is availble? I'd sure like to see more, but I don't think every company has made at least 10 cars within a certain time frame. Do you think Scion made pre-war cars? What about 1970s? 1980s? 1990s? No, no, and no. So that's absolutely foolish to say. * The idea of an aftermarket firm to make a car into a tuner or a race car? This is actualy a less crazy idea, but only because of how to execute the idea. Many tuners do the modding themselves either in garages, and many race car people do the racing mods in race shops. Next, you'll want to define tuner and race car. Tuner can mean anything from a regular car with a racing computer to something almost outlandish and flamboyant. I don't think it's going to be possible for every car, unless you want to make a Lowrider out of a 1960s Pontiac GTO (a weird idea I had myself in playing GT4, except for the Lowrider part). Race cars are highly possible. I don't know how you'd want to pull it off. Easiest way to make a race car would be to give it a widebody look up front and in the rear. It works for a number of cars, but not a lot. I think a lot of work goes into providing a certain car for the game, then making a performance version of it. So it isn't like you can take ANY car and make it a complete race car.
I'm not going to brag, but usually I'm the one who has a bunch of ideas in seperate threads. Thing is, I have some ideas people will normally want to get into. If you can collect related ideas into one thread, do that instead of one thread about wanting more domestic (domestic as in your home nation) cars, wanting no used cars, wanting fewer specialty cars, and the like. I try to offer various threads on various topics, rather than various threads on the similar topics. But, that's just a little suggesting from me to you. Can you dig that?
