Pretty much every single older car (lets say, pre 2000) I've driven the heater would start blowing warm air in less than 2 minutes in subfreezing temps. Usually I'd feel the air getting noticably warmer just driving around the block. In a few minutes, it's turn hot and I'd get comfortable quick.
I've had a 06 and 10 MB, and 10 Miata. The heaters in those were useless for short trips. I wouldn't get warm air in less than 10 minutes. My commute to work is 15 minutes. I'd be downright cold for the first 7-8 minutes, then get somewhat warmer... but only get finally hot and toasty when I was only about 2-3 minutes away from work. So most of the time I'd be freezing cold while driving because goddamn heaters take so long to warm up.
Right now I drive a beater 99' Subaru and this thing heats up almost instanteneously.
Anybody else noticed this or was this just case of particular cars I've had?
