Yeesh...I've seen excel spreadsheets that are more interesting than that spec sheet. I can't say I have gone to a website to "build my own car" in quite some time, but if I saw something like this it would irk me quite a bit. These may seem insignificant to some, but presentation is a huge component to me, and these examples show an apparent lack of attention. When I see repetitions, poor formatting and layout, and graphics/images/interfaces that appear unfinished and took seemingly little effort to achieve, I begin to lose confidence in the product and the company backing it (especially in regards to larger entities -- there is no excuse for it.)
This is one of those sections that I have always felt deserves a significant amount of attention from a marketing standpoint. If I want a car, I am going to go to that manufacturer's website and build it. I want a highly detailed, highly accurate interface where I can configure my car exactly to my liking and be able to view it as I configure it. I want to be able to add an accessory and see it appear on the car, inside or out. I want to play around with the colors. It is the closest thing many people will ever get to the vehicle without seeing it at a dealer and taking it for a test drive. Why wouldn't you want it as detailed and complete as possible?
