They are spectacular cars in immaculate condition and presented in non traditional colours. A wide angle lens as you have used is great for vehicles like this, especially when used from the front of the car. The wa lens distortion emphasizes the forward thrust of the vehicles and gives lots of dof to bring out the fine lines and chrome work.
Which brings us to the bars. I wouldn't want to remove them but I think you might have chosen your angles differently. Image one is different to the later images. Here the V of the angle isn't a barrier, it complements the lines of the car and suggests the same forward movement that the wa lens gives to the vehicles. Here, the bars frame the vehicle and for that reason I like this shot best of the group. That's one possibility.
Another approach might be to go closer to avoid the bars and use more dof. From the exif I see you used F5.6. I know it is a fixed lens camera but I'm not familiar with the lens so my suggestion might not have worked. F11
F16 might have made my suggestion possible while using even more of the wa distortion possibilities of the lens.
With an ILC camera a wider angle lens might have been another approach.
