If I were you I would find the base MF rate for Oct. Then negotiate using that rent charge. There’s no need to bump it up.
Do you only need 7500 miles?
Then you just negotiate on what you are capitalizing.
Once you come to a number, then throw in the Sam’s Club and other programs that I am not familiar with. I’m sure Sam’s Club like Costco will spell out exactly what you get so keep that in your back pocket after you get to a sell price.
It looks like Reignite on E/GLE/GLS is $3,500 and $5,000 on EQS and S-class, but I would push back on Fleet actually being $3,500.
With that being said, I wouldn’t get hung up on the marked up rate if this dealer is willing to go deeper on the discount to make up for it. Being that this is a loaner (mileage?), I’d expect more than 10% off, seeing as I think brokers on here have advertised GLS discounts around 8-9%. And lastly, push back on the “3 YEAR LUXURY PACKAGE”, especially if it has no real benefit (it probably has none).
Pretty sure sams club just adds $1500 to the standard dealer cash? Reignite is $3k as far as I know- I don’t know why the LH rate finder shows $5k. Edmunds shows $3k.
I would definitely push for more discount. Being at $1100 effective on a super base GLS isn’t strong.
A dealer that says they “don’t know the rate” is one I would immediately walk away from.
Just save yourself the trouble and visit the Marketplace to see some of the broker listings on loaners which are much better than this. Most of their posted deals are on higher specs with a much lower monthly. Even if you have the ship, you’ll be ahead of the game on a superior car.
