I thought that someone recently was asking about a premium or SUV code, but I couldn't find the post.

AWD S829900 25% off SUV / premium cars

I think this is a new one, works for SUVs and premium cars. Actually, I think you get a discount on every car class except X, but I'm not sure, didn't test it out.

As far as I know, anyone can use this code - might be able to stack it with a coupon, like free upgrade or something.
