...and I'm a little worried the dealership might try to screw me over.

Some backstory:

In 2021, Chevrolet announced the Bolt EUV -- a slightly larger version of their Bolt EV.

Right after it got introduced, all Bolt EVs and EUVs underwent a battery recall. Dealers were unable to sell these until their batteries were replaced, despite the high demand for the vehicle.

In June 2022, Chevrolet announced a $6,300 price drop for the EV/EUV.

My current car was due for replacement (it's a 2003, lol); I wanted my next car to be an EV; the price drop made this something I could really afford; and it turns out that the EUV is literally the only electric vehicle at that price point that I can actually fit in (my head hits the ceiling in a Kona, for example).

In June 2022, I attempted to buy an EUV, only to find out that there were waitlists everywhere because the price drop increased demand, while the recall decreased supply. As such, I put in an order for a 2023 EUV with a deposit.

2023s went into production in July, but it turns out they're not made in order (which makes sense: the factory makes batches of similar types) and it also turns out that different dealerships have different "allocations" which means that they only get so many of a certain type of car -- even if it's been directly ordered by a customer.

I didn't know this at the time of ordering, but, the dealership I went with had a very low allocation for EUVs.

I have waited this entire time (which is not uncommon), and my car has finally arrived at the dealership. I'm slated to pick it up tomorrow and finish the purchase.

My concerns:

The dealership knows right now that they have me over a barrel. I've waited eight months for this thing. There is no other available inventory anywhere, as the EUVs sell immediately or, in most cases, are already spoken for before they arrive due to waitlists. People trying to get them complain about huge markups because of this.

I have a "motor vehicle purchase agreement" from the dealership from when I ordered the vehicle and made my initial deposit. That paper shows that I'll be paying MSRP for the vehicle, which I'm happy to do.

My question is: is the dealership going to try and make me pay something different, knowing that I'm not going to walk away from this? I feel somewhat comfortable that I have an agreement for the MSRP in black and white, but is that enough?

My other question is: is there some other way they're going to try to get one over on me? Something more subtle or that I don't expect? The last time I bought a car was ~15 years ago, and I pretty much stood there while my dad did the talking (also the car was used and super cheap).

I will be financing a loan through the dealership to pay for the car.

Basically, what can I do to make sure tomorrow goes as smoothly as possible? I'm hoping that it's easy, cut and dry, and there's no funny business, but I've also heard some horror stories -- especially from people trying to buy the particular car I'm getting.
