Well, went to local BMW dealer, got quoted $850 for a base 540i service loaner. That was best number for 3 dealerships, so that is out of question.
Went to local Audi dealer, looked at a 2018 Audi A4 2.0T Premium Plus $49000 sticker, they gave me $4000 off sticker and another $1000 rebate.
Final monthly payment for 36mo/10k a year no money down was $660 (taxes tags enrolled). That was the best they said they could do.
Yes, use the search here to see about other deals people are getting, then read the comments to see whether it’s bad or good.
General rule of thumb is 1% of msrp being the monthly payment. However audis don’t lease well so if you can get close to that 1% or right on. Then pretty good if dead set on that car.
