The advantage for me was that I could buy a new interior and seat kit from Airtex to fit the new seats. So the new seats I got are an ugly brown, but that didn't matter because I'm replacing the front and back seats. The frames get reused, but the foam and fabric is new. When I ordered the seats and carpet about 5 weeks or so ago, they said there is a 16 week wait to get the seats! So, I'm still waiting for mine. In the mean time, I've added an ADSB transponder, new AeroLED nav/strobes, and I'm currently installing a JPI 730. Next purchase will be an autopilot once it's certified. Love this Mooney!!
If you guys are interested in the AeroLED lights, they are super easy to install. The mounts fit the same three holes as the old lights.
