Interesting comment, Dimitri. My first reaction was to think "better get one", but then I remembered we rarely go below 0 C in Nova Scotia so maybe there's no need.I remember my automotive engineering elective I took in university.
90% of engine wear occurs during startup.
If it's below 0 F or -18C, I plug in.
If you reduce the warm up time from 120 seconds to 20 seconds by having it plugged in for 2 hours, that adds to your engine life.
My 20 year old civic engine that still runs like a clock up in the Canadian north has served me well.
Very geography dependent. They wouldn't spend the money to put one as standard in a vehicle destined for Florida, while one in Toronto is likely to have it as standard. My recollection is the Canadians get some nice heated features like wipers and a block heater, while those south of the border don't.In the states, it's an add on item- Not sure about Canada etc.
