For Al Daid... two options.
1st. Go down the Sharjah/Daid road. Get to first roundabout and turn right...after three or four KM you'll find a whole load of scrappers. Rainbow Breakers on the left always had good assortment of series vehicles, early Disco's and Range Rover Classics.
2nd Opion. Hit the same roundabout and turn left....at every roundabout, intersection etc go straight over untill you see a series I vehicle perched on top of a 20 feet tall tower...it's the best clue to what lays ahead on the left hand side. Mostly series vehicles but some rare Menarva's and series III Gun ships from Saudi.
