Here's a write up I did back in 2009 when I installed a radio in my wife's 2009 Ford Escape hybrid.
2008 Ford Escape - Batboard My post starts at number 5 and goes down from there.
It has the sun roof, so I included measurements and photos on doing the NMO install.
Not a lot of room in these vehicles, but not too difficult to install in. I'd strongly recommend the permanent mount NMO install, on top of a vehicle like this with a good ground plane you get really good performance. As an 8 year old vehicle, you are not going to impact the resale value by doing a proper antenna install. The trade off is in the performance.
8 years now with this install, other than getting rid of the amateur radio and putting in a CDM, I haven't felt the need to change anything. Still happy with it after all these years.
