My first car didn't have a heater now all cars have heaters and we expect them, I think it's the same with air con. My last five cars have had it, not by choice they just happen to have it, and now I've got used to it I wouldn't like to be without it. It can get quite hot in the 5 in the summer especially on the drivers side with the heat from the exhaust. All this talk about air con is making me look forward to the balmy days of summer again.
