I’m not an expert on Lexus programs and incentives, but that kind of payment (with an amount due at signing) for a sub 50k car sounds pretty bad to me.
With a payment like that, you are way off better getting an RX or GX. December to Remember is coming soon, I recommend waiting until then and you can get a much stronger offer under 500 with zero due at signing
TBH it’s pretty scary how little effort people put into saving their own money. “Is this a good deal?” The answer should be obvious after 5 minutes of reading this forum
