[recycled sixtie]

We have had -20C or about -10F for a whole week and our Camry and Lexus RX350 both start up no problem in an unheated garage. The RX has no block heater but there is no need for it.

Newer cars and suv's are way better at starting than the older cars. Having said that my 1958 VW bug would start no problem in -20F with no block heater. Loved that old car but had next to no heat when the car was running.
