Hi all my turn to ask a few questions, my wife has seen a 94 440GLT. Is the engine a Volvo engine as it bears a resemblance to a 2 litre GM engine fitted to Camira's and Daewoo's in Aust. and it has large amount of Delco/GM engine sensors. The AC is not working in this car suspect gas loss is this model prone to certain AC problems? Thanking you all in advance Joe
