I definitely felt like new was my only option to get what I wanted (gray, GT+PP, AA/CP), but the best price I was able to find was $30.9k before TTL.
If I decide on the '17, I do still have to add AA/CP for another $400 unless I DIY it to save a couple hundred.
I tried haggling to get AA/CP installed on the '17 with little to no charge, but no luck.
I wasn't able to find many Gray 2017 GT w/ PP in my area, there was a Gray 2017 GT w/o PP at 29k miles for $24.3k through a private seller and that was sold in 5 days up on cargurus. The only CPO in my city is a Silver 2018 GT w/o PP at 37.8k miles for $25k. The only other CPO with PP I could find within 200 miles are Red 2018 GT w/ PP, 4k miles for $29.5k, 10k miles for $28.5-29k. At these prices, my thought was to spend a bit more to get a new '19 GT w/ PP in Gray.
I'm having them send photos and videos to see if there are any noticeable wears to be concerned about. If not, I'll probably proceed with a purchase.
Thanks guys!
