MASHALLAH.. zabardast ride you got, when you left Saudia??... even am in love with 7 series but you know when you have too much family committment than you have to only think about the family and yours interest and priorities are replaced by family priorities... I born and living in Jeddah, just went to Pakistan for doing my graduation and post graduation and returned back.
So you already have idea what am talking about flat tires and Saudis and you will also agree with me...
Abbasi bhai, regarding battery you can use Dry battery, you will be tension free for filling and leakage of acid... For reference my both rides with Maintenance free battery... Here most of the Maintenance free batteries are in black color and from AC Delco there is a chance you can find Correct year batteries.
