Chevy Silverado is probably one of the cheaper trucks in Qatar to maintain. Since the vehicle is in its 6th year, expect more repairs/part replacements. Then again, it all depends on how well the previous owner maintained it. I have heard the A/C in the Chevy trucks tend to struggle during summers. It's a great off-road vehicle though with great towing capabilities as well.

Overall, the Silverado is a decent buy for a 4x4 under QAR50K, but don't expect Japanese reliability.
