Let's be kind and assume that the GT500 cars were Gr.3 and 450,000cr, and the GT300 cars were Gr.4 and 350,000cr, rather than being priced up because of their fame.
If you're willing to pay ten bucks on microtransactions instead of this pack, you'd get 750,000cr. That means Sony would have to price the pack considerably cheaper than the microtransactions it wants you to buy if ten bucks would get you a pack of multiple cars.
Your ten bucks wouldn't quite cover one of each type, but you'd be able to get two GT300s.
Definitely useless. There's a ton of other wish-list threads and we don't need new threads with every single little thought someone gets into their head.
I would pay for a remastered gt4 in the PlayStation store available for download. PD have a lot of things to fix in gt7 before I would be willing to pay them more money for any DLC in this game
