I own Cherokee Classic 2001. Spare parts are available from both the company - Jeep Al Mana - or third party. For third party, I shop at Salamco Trading or Al Faris in Bin Mahmoud(?) near Jaidah Flyover, or Al Faris opposite Landmark Malls.
Mechanics/garage, I rely on American Tech Center, now in Barwa Village, Wakrah.
