thanks for everybodies interest. i ended up trading it in for a cr-v. i needed something bigger with the new job. i have to lug a lot of heavy stuff around and the hybrid wasn't going to do it. it was getting really poor gas mileage with the added weight.

the rear parking sensors are from echomaster. i have installed them before. there is no need to remove the rear bumper. just have to drill the holes with a hole saw and then fish the wire to the rear tail light. it takes less than a hour from start to finish.
