Wife has Cliffords "Intelistart" upgrade on her escort cossie. Best thing ever :D :D :D But its not cheap and she added it to a much bigger system.
Set the A/C in winter to war up the car and defrost it while everybody else scrapes the ice from there cars. Sets it in summer to chill the car before she gets in.
It wont start if you leave it in gear, little laser grid running across the base of the gear stick shaft and wont start if bonnet up. :)
Engine will stop after 20mins.
Engine will start itself if outside temp gets to low and if battery power level gets low. Havn't tried the temp or power thing yet, it hasn't got that cold and i never let her battery get power get low.
Engine stops and alarm has a fit if try to move the car without the correct fob and key.
If you rev the car over 2000rpm (without the correct keys) engine stops and alarm goes mad, put the car in gear, push the brake or generally breath to much and the alarm system will just go in to one. :P :P :P :D
And its great for freaking people out in Tesco's carparks. :D :D
Start the car up, drop the windows and turn the headlights on. Works every time. :D :D
