car dealers

Can anyone suggest me some reputable and trustworthy car dealers in eastern province area of KSA? I would like to start doing a research about prices for new or second handed SUVs as well. What kind of vehicles would you suggest to someone to buy in terms of reliability and availability of spare parts in case of damage.
In what things should someone pay extra attention prior buying a new car and what banks provide car loans with low interest rate?
thank you
