Ziebart did my truck last fall.
Only thing I don't like to much is the remote buttons sometimes get stuck and cause the horn to beep.
Keep in mind I got the cheapest one they had since I did not want the alarm and all the other jazz. YMMV.
I forget how much I paid, but I got 2 remotes and free batteries for life for the remotes.
I also made an appointment to have it done and they had it done when they said they would.
Wax Werx in Castleton does them. I love mine. Best accessory I ever bought for a vehicle. Prices vary from $200+ up depending on the functionality, but then I've had mine for a while.
Zeibart in greenwood has tinted windows on two cars for me years apart and the service and final product was great. If I needed a remote start I would probably go to them.
Wax Werks installed a car alarm on my Grand AM. I would NOT recommend you let them mess with the wiring of your car.
Their wiring job was terrible. At the time I knew a guy that had worked at Best Buy and he was kind enough to correct their mistakes and sloppiness of an install.
One HUGE example was one of the wires that needed to be hooked into the fuse panel was held in place just by the fuse itself.
