i voted yes, although it is not a must. it is a conveinence item. i have one and it makes it easier since I am always rushing around place and dont have time to let it cool properly. that being said, if I am on a hill or not somewhere flat, I just turn it off.

its also nice to be able to see battery voltage. again not NEEDED, but nice.

 

yeah, I have one, but rarely use the damn thing. I usually have the patience to sit there a few minutes. It is convenient though if I beat on car and have no time, like speeding to get to a movie on time! LOL

 

Isnt necessary, but id suggest getting an upper end alarm system for the car if you own an evo.....I have a Hornet alarm and it has integrated turbo timer function built right into it, and when it shuts the car off it automatically arms the alarm system....
