Car rental (Doha)

Hello all,

I'm looking into getting a car for myself and wondering if anyone here has some experience with long term car rentals. These appeal to me because, as far as I understand, insurance and maintenance are included with the price. Are there any rental agencies that I should visit or avoid? Or am I better off just buying a used car? My budget isn't too high, I don't need anything fancy, and I'd prefer to not take out a loan

Kind regards
