I doctored up one of the top revisions, and smoothed out a few lines. I removed the exhaust tips simply because they were crooked... we all can imagine what our tips look like.

Anyways, I made the transition between the vented area and the bumper a bit more gradual. Also, I made the area above the tips extend straight across, instead of arching upward.

Personally, I love the more aggressive bumper. To me it blends well with the three strakes on the front fender. A great design (on cars in general) is when certain design elements are repeated throughout the body. That's why I've always said we needed hood vents like the new SLK 55.... thee strakes, and it would blend with the fenders.

The bottom two are BASICALLY choices that we already have access to, a-la CTD (click on the SSB SRT-6)...
