The construction of the bike rack looks very sturdy and I also notice there are even brake lights on there. This tells me that this product will not be cheap. I would probably go with a third party product since there is already a pretty good market out there for them. Check out
Thule and
Allen Sports. I don't think you can go wrong any way.
For first time buyers, the only thing I would advise against is buying a trunk carrier. I once made that mistake and I paid with scratch marks all over my car paint. I think the same goes for roof racks. Just spend the extra money and do it properly with a bike trailer hitch.
