Hi Bastien,
My car came in saudi arabia in oct 2005. one of my friend imported it from Japan.sand, dust and heat are really big problems here.on ecan easily ruin his ride if not aware of these things. driving on high speed through a sand storm very badly damages the front of cars especially paint, headlight glass and plastic work on bumper etc.if you r loosing little coolant in desert heat the engine may quickly heat up. once i was going to Riyadh and i faced a sand storm.despite of the fact i slowed to below 40kph, there was damage to paint work on front bumper.i ll soon post pictures of interior which is satisfactorily nice.
thanks for your intrest.
