car under loan will nto be allowed to go out of the qatari borders unless u get a qatari man to guarantee u in the bank or 2 expatriates who have accounts in the same bank to guarantee. this is first. 2nd families are only allowed to go together in one car. if a cousin, he or she wont be allowed to go with u out of here. 3rd, u need to make insurances for the car. 4th u need visa to KSA and emirates in advance. 5th it iwll take u 6 hours to reach dubai. 6th, goodluck and enjoy :)
