i found out the hardway to sell my BMW but eventually sold it. The German car market are small group of people mainly from Qatari or european countries who appericate the brand. most people think its a high maintenence cost to keep a german car. which is a myth.i was able to sell mine quickely using these online website. Carsemsar service is better then Qatarsale.
