Buying New Car Insurance

I have been without a vehicle for over 10 years since I went from temporary resident to permanent resident and could no longer drive a foreign-plated vehicle. If the car dealership can get its act together, I will be getting a new pickup truck next week. Then I will have to get it registered in my name and buy auto insurance.

Does anyone have recommendations for an auto insurance company to use, or one to avoid? I will be wanting to get extensive coverage… third-party liability, on-site legal representation, collision, comprehensive, theft…
