I don't know why but before I got my autostart it took a little to get started but now either using the remote or the key it starts right up! Used to take like 3-4 seconds now its just .5 seconds to start. Not saying not to get a block heater just letting you know what I have experienced. How many people remember to plug your car in? Then in the morning you forget about it, until you start pulling out of your driveway and you see your 50ft extension cord from your house to your car pull out of the house wall, or worse drag that cord to work with you! Something to do if you want to plug it in all the time is to get a hook that will keep your extension cord plugged into the house (screwed in right next to the socket and wrap the cord around it)
