Jessica,
If you want to work in the marketing world with your degree, then consider this as CONSTRUCTIVE feedback.
Firstly spelling mistakes and poor grammar are unacceptable.
Secondly don't treat your targets as idiots or fools. In this case it is not about aftermarket accessories nor even specific aftermarket accessories. It is about ONE type of aftermarket accessory.
Third context, you should have known the difference between Custom, OEM & aftermarket (although still don't think you've grasped the difference).
Lastly understand your target audiences, You said 4wd & SUV accessories, but your extended mirror survey has little to do with offroading (which this forum is predominately based), and more grey nomad caravaner.
I realise this just a topic "given to you", however you should think of it as no different from any customer coming to you with a job. Research and attention to detail are paramount, not just data correlation.
I am not intending to badger you, but I can assure you with some of these things I certainly have been hammered with during 20 years in the corporate environment (before I got out ). Maybe watch a few episodes of the Apprentice & you'll see what I mean
.
Good luck.
