i know Clifford has a system that will detect that the e-brake is up and the car is in neutral. i went to tweeter and they wanted $250 installed for it on my Concept 600. which i think was $100 for the remote start. $50 for the module since its a manual. and $100 for labor. thats not too bad if you ask me. remote start is nice when its cold out. my girl has it on her 2000 Celica and uses it all the time in the morning. you just hit it, go get ready for work, and when you go out your car is warm and ready to go
