Don't know about you guys, but i couldn't live without my turbo timer... I always leave the car running, even if its a casual drive down to the shops... My alarm work fine with the turbo timer... I switch the car off, press the button and she locks and then when the car switches off its immobilised...
In the mornings i use it to warm up the car... I start the car, turn the key off and set the turbo timer for 5:00 mins, lock the car and go back inside to finish getting ready... I'm no Captain Cold-Cane...
