I paid ~$USD230 FOR the kit and installed myself.I went to my local dealership here is Riverside, CA and asked how much to install AA/CP. I was told $420 on my 2018 GT. Wow really....
I am thinking to spwnd on the labor. I can do it myself but looks like i will be getting my mazda connect replaced under warranty this week. Cobsidering the hassle it was to finally get it replaced I don't want to give them an excuse to not cover it if it is faulty.By the time you add up the different steps, 2 hours is not an unreasonable amount of time to charge. Labor rates are $135 an hour in some locals.
$200 for parts and possibly $250 for labor is not out of line. Putting the foam on the cables is tedious. The service guys have to be more careful pulling things apart as customers are looking for mistakes.
And you want a warranty with that too, right? If people think the price is high, then find an independent repair shop or DIY. Try pricing out brake jobs... that is even more nuts, IMO.
I did mine myself.
