Yes be aware that these appear to be textures only, using the same models already inlcuded with FPSC. Not really the best approach to take IMO.
And I would have to agree, the textures aren't that great, and don't match the geometry of the models in many cases.
Re-texturing CAN be a great way to get more mileage out of models, but I don't think this effort is worth $14. For this amount of money they should match the quality of the models from TGC. Considering the price for FPSC Model Pack 1 is $19.99, which I think is a fair price.
