Let me share my 2 cents worth from my experience of doing marketing for a company dealing in multiple marques regionally. Firstly, it depends on whether you are shooting for the car brand itself, for publications, or for the owners, etc.For the latter two, there isn't much restriction on how you can shot the car. But if you shot for the brands themselves, you would be given a whole document with regards to the whole CI on what angles you can and cannot use.
In your picture above, the choice of background is nice, since the RCZ is targeted at "urbanites", especially PMEBs who wants something really different. However, since the RCZ is really about her unique outlook and appearance, the angle you choose hides all of it. The size and proportions of the car appears compact and squashed. Buildings over the car also hides the contours of the roof of the car which is another unique point of the RCZ itself. Reflections is something that Brands are very particular about. Unless a reflection is intentional to bring out the curves of the car, its better to do without. The reflections of the buildings in this case also distorts the rear left tail lamp of the RCZ.
However, you have done well in showing the rims of the car (especially the front left). The position you took is also right as it shows all 4 wheels. Brands hate it when the photo shows only 3 wheels which gives the feel that the car is on tripod.
There is a whole lot to automotive photography. Then again, these are just some pointers which I can share based on my experience in this industry. Like I mentioned earlier, it really depends on who and what you are shooting for; rules or no rules.
Cheers~
