Three of my favorites from GT5 had some issues so far untouched. The first being a modeling problem. The other two are poor models because of the cars they choose to reference.
Dodge Challenger T/A '70 - Missing passenger side hood emblem. It's a small thing but I thought they could have fixed it.
Chevrolet Camaro Z/28 '69 - Not a real Z/28 or at least a factory correct one. The versions in GT2 and GT4 were much better than the new premium model.
a. The grill, head lights, and tail light panel are wrong.
b. The model has after market (or maybe dealer installed) Long tube headers instead of factory manifolds.
c. The replacement blue tinted windsheild seems messed up in GT6. It looks black now instead of tinted. (The new lighting engine makes it look dark and they didn't bother changing it)
Shelby Cobra 427 '66 - Now this thing is just plain weird. It may be the real deal but it sure doesn't look it. And again the models from earlier games were much better.
a. The biggest problem for me is the interior, it's red regardless of exterior color. Most Cobras have black interiors.
b. The car has a hood scoop that doesn't appear to be funtional, and a air spliter in the grill. Cobras normaly have one or the other, not both.
c. The expected oil cooler isn't present. Even 428 street Cobras usually have it.
d. The wheels and exhaust are strange, not wrong necessarily, but added on to the other things make this one odd car.
Am I just crazy or should PD pick proper cars to reference before they build premuim models? And how are cars getting worse? The premium '07 Mustang is worse than the standard '05 from GT4. I only care because I love Gran Turismo, and I love these cars so I want to see them at their best.
