buying an used car in Riyadh

Hi, I have been in Riyadh for almose 1 month.

Now, I'm thinking about buyng a car.

Is it good idea to buy an used car at used car auction in Nassim area?

I was going to buy a New Jetta from VW dealer. But there was a Protected content 323i

(40,000~50,000km and minor scretch). I couldn't check there was an accident.

I don't know which one is the best deal. I'll stay here for 3 years, I have to think

about re-sell value. The prices is not that big between both car.

Please share your experience.

thank you
