walla man mabrook in advance but think of other things too:
alsaaif is really bad i am telling you from personal experience plus if anything happend to the car you will stay at least a month before they do anything.
also if you want to send a complaint, you won't get a good answer. remember range rover now is american not german from BMW any more.
the only german part in the range rover is the transmission which is BMW transmission and everything else is a mix. some from Isuzu and some from daihatsu and some american from jaquar.
one last thing:
turbocharger + hot weather + saudi arabia = BYE BYE CAR
of course this is true if you use the car always or on a daily basis, i had a friend in australia and his car is in the bye bye now. the weather there is almost similar to jeddah in summer where my friend is.
have you ever asked yourself why some companies dont bring to saudi the turbocharged models such as subaru legacy GT2.5, the impreza one too, VW 4mothion models and R32 GOLF.
it's because they know for sure tthat they could not guaranttee the car quality and useful life.
also the range rover is wellknown for heating problems without having the turbocharger so consider these options before you buy cuz really you are paying too much money and you deserve to enjoy it.
you also say that BMW will lose 100K's of it's price ... so what
are you going to buy it for a couple of month then sell it hell no ... you will keep it till the WHEELS FALL OFF
the mercedes is the best choice if you really don't want the headaches of the other two cars specially that you could screw it's brain out without worrying about anything. and if the car dealer pissed you off for bad service you could always e-mail germany and they will respond in a matter of 7 business days.(of course the problem s usually take a month or two to be solved)
again dont mind me i am not trying to scare you but seriously if i am paying money i want value and peace of mind for it.
cheers
