I also recommend doing more research and asking for hi-res photos. I have found, in my years of shopping on eBay, that when someone takes large photos and shrinks them down, the images look detailed and look right, but if the real-life object is many times larger than the online image, you can often see a loss of detail in the real-life object - including holes, dips, distortions, surface defects, etc. If it's a fiberglass object, you won't be able to see if the fiberglass used is the wrong kind of material (e.g. mesh is better than cloth) and if the fiberglass has delaminated from the resin, creating annoying air pockets, rending the FG useless where it was supposed to help provide some structural strength.
A lot of these things don't show up in photographs. Especially if the kit is white and was photographed in bright sunlight light or if the object were overexposed, detecting flaws in the online image is near impossible.
If the interior or underside of the casting were not photographed, there's a world of information you would not have.
One last thought is that some take photos once and use those same photos in peddling all their products. You then never see an image that represents what you're getting. eBay doesn't really regulate against that - and so long as what you receive bears a certain percentage of resemblance of what is advertised, eBay may not rule in your favor if you find what Luke Skywalker once said: "What a piece of junk!"
