I have narrowed down my next car choice to be a used Ecoboost Premium 2015-2017. Any issues or things to watch out for that any of you have experienced? Any recommendations on what to look out for when inspecting/testing the car?
Also, would appreciate any pointers on where to buy private owner used vehicles as I have only seen ex-fleet cars at my local dealers/sellers/websites.

 

cars.com you can narrow search to individuals
craigslist as well
ebay
certified pre-owned
shop them all

get the carfax report every time
add a ESP after purchase

 

Don't buy a 2015! Buy a 16 or 17! The 15's had problems that were corrected in the 16 year!

Your going to love owning an Ecoboost! Its the best Mustang ever made pound for pound! Long block is good for a whopping 500whp! Don't even think about how much TQ that is! Its 604lbs ft of TQ @ 5000rpm! 575HP Flywheel! Depending on the size of the exhaust housing is on the turbo! The smaller the exhaust housing the more TQ you'll make! This guys housing is a little too big and so he's only making 464ftlbs of TQ! Its call exhaust A/R! A good A/R is typically .81!

All you need is a $4500 turbo kit!
