Some of the other members have been able to install one. I believe the consensus is that routing the wiring in the hatch it the biggest issue.
Anyway - ended up buying my Fiesta tonight. I got a 2017 base ST in white platinum, really like the color a lot. I think I got a pretty great deal, I was able to get a few rebates and with negotiation got out the door for $18,8xx - not bad for SoCal I think. Had to do some driving around tonight and put about 70 or so miles on it, it's certainly a blast to drive. The craziest thing is how direct the steering is, no play at all, nudge it and you're going that direction.
I can't wait to dive into the forums and start seeing what everyone's doing to these things. Thanks again for all the info and help in this thread!
