You bring up a huge issue I missed.
Honda and Toyota on a macro basis steer clear and don't lend to sub prime. The results of not lending to sub prime on a macro basis is higher resale values for Hondas and Toyotas.
For the past decade, Nissan did sell to sub prime on. Macro basis. Selling to sub prime results in lower resale values, as some of these sub prime vehicles hit the repo process, and other intangibles.
Honda may have a risk to resale values if they merge/aquire Nissan.
And of note, published repossession statistics are worthless in many cases because it is simply a number count, not a mathematical model that divides number of vehicles sold against number of repossessions.
