Dear Zy,
Thats not a good deal, if you ask me.. i have been looking for one myself.. but amercian or canadian specs dont really do that well in here.. you can go for a second hand car but directly from the dealers. they will give you a proper service history and you can also find out if the car has had any accident or repairs.
Secondly the cars being sold in Awir or sharjah used cars market have a lot of superficial cars, by this i mean that there are cars which have had a major accidents and repaired and repainted just like new.. infact much better than the ones available in the showroom but that doesnt change anything. there have been cases where i have found out that even the digital meter was also reversed on the car which means nothing is what it seems.
So i woud suggest that ifyou are going to buy a second hand car either buy it from a dealer or from the person who you know well....
Best of luck with your search.. do let me know how it goes.
PS: i just posted some information on an Altima 3.5SE that i saw yesterday... may be you might be interested.... you can call Santosh in used car.... was a great help to me
