The 24 CT is going to be much harder to find a deal on than a 23
Except for whatever brand has a Costco Auto special incentive (eg Volvo now, previously Audi/GM) they are iust lead generation for dealers, not necessarily a good deal like they proported to be pre-pandemic.

TL;DR most Subarus make more sense to finance than lease, and the advertised lease special is never worth the paper it’s printed on since the small print says it excludes taxes and fees and blessings.
You can look in SIGNED! For other AZ deals to better understand the fees if you buy/lease there.
