Seasons Manipulate Car prices in Saudi

as we all know that price of petrol is a big influence on car prices, we've seen GMC trucks take a leap on price matters from 11 thousands to 40 thousands letter-ally speaking , but that a one time thing to happen, but to see the price fluctuate every year and on a specific season , that got to be written about, so a car buyer would know what to buy and when to buy, in winter you need to stay away from 4x4 cars, cause the price is up to the roof and it's mostly over priced because of the seller greed and also because the buyer won't keep it for long so he will pay whatever it takes to fly away from town on this car he just bought and will sell afterward, giving him freedom to give it hell and not to worry about workshop or any spar-part issues, so 4x4 is not recommended on winter season, secondly during Hajj season try to avoid the SUV cars because many workers in the field of transporting of Pilgrims are competing in the market, last thing avoid the cars that has been used by a Kdad cause he has no mercy for the car whatsoever, take my word.
