It is that time of year again...
I just had to scrape my windows for the 2nd time this year today. Loving my 1000W block heater on the 1.2L engine on the Mirage. 20 minutes gets it up to 90F.
This is the one I'm using, and its even pretty cheap right now on Amazon, only $37.66. Its usually about $45-50.
