just mention(paste the link) one of his advertisement
so that we can concern about him.

in qatarliving most of the people sell cars--who are doing business.
so be careful to buy a car!!!
if your car's engine, gear, chasis is good, than it's ok to not angry with the seller. because some people buy cars and after they found the car had dangerous accident/ gear is not good/ engine is not ok etc...

so next time check the car on computer, that's the best thing to do!!!
