I put my car on Qatarliving.com a week ago, it sold after two days to a lovely couple who were genuine about buying it.
I would caution if you get calls from showrooms here, I did, and in my experience they take your car and basically use it like a piece of sh*t, and when you get it back it's filthy and there is a bit more mileage on the clock than when you gave it to them!
Also, being a woman and british, they clearly tried to fleece me by telling me i'd not get much for the car, which was a truly dishonest thing as I've now sold it for a brilliant price.
I think they're crooks. So. My advice is, good you put it on here, only see personal buyers, not showrooms, and also, put an add on your company website/souk like QP have one, and also use a paper ad in somewhere like Megamart notice board... A friend did that for me but the car sold via QL anyway. Best of luck!
