CADalyst 3D has over 3,000 models with more added daily. Members can download models and enjoy blueprints, textures and updates all for free. Membership costs only $3.65 per month or $40.00 per year. However, their model library is not open to the general public; you have to be a member before you can have access to the model library.

CADalyst 3D does offer some free models, tutorials and plug–ins. However, for full access to a great library, without membership obligations – check out Turbo Squid.
