A&Q about 350Z
Q:
Dude $225.00 is not a bad price. I'd pay it. From what I've seen from a kid in my class they are most defentily worth it. You will get your $225.00 back in the first two weeks that you use the thing. I plan on doing it to my Z when I get it done.
A:
I agree that $225 sounds like a decent price. I installed a remote start in a Pontiac Grand Am last December and it took me 3 days to complete the task. Just make sure that whomever is doing the install has done a Z before - lots of wires that need to be found and spliced. Also ask if they solder the connections. If not, the unit may cease to work after a couple of months.
