I just paid $25.5k after tax, title and tags (no trade-in) for a 2019 S 6MT with 8,300 miles. 2.49% APR
They priced out a new 2020 S 6MT for me with 15 miles. MSRP was $29.6 and they brought it down to $25k (before tax, title, tags) with 0% APR.
Difference in monthly payment was about 2 dollars.
I went with the used one because it had the better warranty. CPO adds 1yr and 12k miles and 2019's had 6yr 72k mile warranties compared to the 2020s which only have 4yr and 50k mile warranties. Since the 2019 car was only 9 months old with 8k miles it came out to a 75 month, 76k mile warranty which more than made up for 8k miles in my eyes. (I believe the 2019 vs 2020 warranty comparo is accurate, I'm going off of memory).
I also got the dealerships 5 year care package (bent rims, curb rash, blown tires, dents, windshield chips and cracks, etc all covered) for half price.
To be fair, the finance manager and sales person are both close childhood friends of mine.
