@Jrh710 I was able to get slightly better numbers in Oregon. The S90 that I am looking at is ~$73k and I got the net down to ~$52k. Keep in mind the one I’m looking at is a T8 (and there is no sales tax in Oregon). I told the dealer that I had A Plan (because I did have a friends and family code), but A Plan ended up rejecting it. I am working with the dealer now and I think they’ll still give it to me because they are eager to sell the car.
Guessing that your advertising is $500, it looks like you got about $2,500 under invoice, which IMO is real strong. Factoring in the buy rate at 0.00025 and a RV of 51%, I come up with exactly what you posted, using $298 for license.
If you want to get fancy, post up 4 refundable security deposits of $600 each and drop your MF to 0.00005 and payment to $586 including tax.
