It's cool that you can buy cars that you can't normally (from a friends garage) but it's also kinda gay because I thought you would be able to personally say like I'll give you this corvette C5R and 500,000 Cr for your Esperante. That's the way I thought it was going to be, where you can trade cars between each other and if you decide it's an unfair deal you can add in some money on top of a car. Hopefully GT4 will make some improvements on their trading.
