I haven't got a a 4.5 but I did have a Speed 6. In my opinion GET THE AIRCON whatever it weighs. It don't half get hot in the cabin without it - even on a cool day. Also it will make the car much more resaleable when the time comes. Paul
Not sure about the weight but my aircon works ok (ie if you like freezing air on your crutch). Selling a cerbie without aircon is an uphill challenge. Especially if it is a newish car. So I wouldnt worry about the weight , I would get it.
Got to have the aircon. The entire dash area and tunnel get warm from the engine and keeps the relatively small cabin all very cozy, and that's without the sun blazing in.
If you don't get the aircon, I suspect you will regret it on the first sunny day. Heatsoak into the Cerbera cabin from the engine can be pretty fierce and it's only made bearable IMO with the aircon going full blast.
