It would be much better if it was set up like it was in GT4. Including putting the prices back to what they were in GT4.
I agree with Tornado in this one. GT4 used car dealers were much better... 2 dealers according with the car era, better description and all.
The used car dealers was present since day 1 in GT games. If they remove it, it'll be a BIG, ENORMOUS FAILURE.
The game will lost 30% of its appeal, because it'll be just like the other games. Buying an used car, its a process that have a lot more soul, luck, than buying a new one. GT5 car collectors may agree with me. Finding that special car, in all original colors, its a fun minigame. GT5 won't be the same without that.
For me, the quantity of rare cars in GT5 isn't enough. You don't see a Honda Coupé 9 every week. I bet you can take a year to find one for sale. This is where, I think the dozens of Miatas and Skylines have their reason to exist. As more common cars, they flood the used car dealer, making it tougher to find that special cars. My VW Nardo, My X540 Chaser and my only 1 ZZ-II are special cars for me, because it took a lot of time to find them. I'm playing GT5 since the day of the release, and I only found 2 Chasers in the UCD. I think this is healthy to the game, because it keeps the original format from all GTs and adds value to rare cars.
Those who play GT since the first games, probably don't mind to have to search for rare cars.
