: I presently live in houston tx weres its not quite as hot but I can tell you both the ac and cooling systems are up to par. Have owned this 5er for 3 years. as for other gremlins,the cables that transmit power from electric motors to actuators in front seats seem to alsways need adjusting also had problems with rough idle. replace intake manifold gasket and seems okay now. get standard if possible much more responsive and have heard no problems from other owners. Sorry my car is black and not presently for sale. Also do get a car with less than 100k so you will be covered under bmw engine warantee.
