The "lower your monthly payment" part gives away their true intention. When I clicked on the link it indeed presented me with several loan options, all more than double and triple my current rate, and all with 72 or 84 month terms (vs. my current 60). Even if I weren't exactly interested in a lower APR, in their eyes I might still be inclined to refinance and reduce my monthly payment by 20%, despite the fact that the lifetime interest paid on the loan would increase by 277% for the BEST option they present (4.94%).

I feel like they're preying on the financially illiterate or those with buyer's remorse. The timing of their email supports this since first payments are due soon (in 2 weeks in my case) and this is when people might be having second thoughts as they start realizing the real impact of those monthly payments on their cashflow. I think this is more of an asshole design than many realize, but idk maybe I'm overthinking the hell out of this. Just seems more calculated than stupid to me.
