Hi, I’m new here too, wait a little more for the pros to weigh on, but from what i see, u didn’t negotiate much on the selling price. ~1000$ off is meh, 10% min off is ok’ed here. more than 12% is patted on the back. so you lost close to 1500 there. Rest is great. Also try and avail costco cash offer for 700 off. Here’s a similar deal on a LT for better idea.
4850/24 = 202 is good, <1% MSRP per month payment is generally considered good, nothing to feel bad about. but could’ve done at 2650 if you factor in 700 costco cash and another 1500 off selling price with negotiations. Also, check if the money factor is from direct GM financial and is not marked up by the dealer.
