Reliable mechanic needed for Jeep Cherokee (Riyadh)

Hi all,

I have a Jeep Cherokee with a mysterious problem. I've taken it to the Jeep dealership who have responded by saying they cannot find the problem and they cannot fix the vehicle. A car dealership cannot fix it's own car?

Anyway, I know local mechanics specialise in particular vehicles and I wondered if any one knew of a reliable mechanic who specialised in Jeep cars?

Suggestions appreciated.

Thanks
