All Credit Tier Deals

Hello all. Not sure how to look this up. What dealers finance groups are offering deals across all credit tiers? I believe Nissan does but not sure of others

context: My wife is coming out of a porsche Macan. 3 yr lesse. She botched up her credit with some late payments. Don't want to hassle on deals and then NOT qualify for the deal based on credit tiers.

thanks in advance.
