It's totally dependent upon the local market, but the key is to research your area and find a dealer that's willing to look long term instead of short term profit. The long term dealers will want to create a relationship with you and foster your loyalty. Where we are at we saw anywhere from $3k to $5k markups over MSRP for the vehicle we wanted (2022 Hyundai Tucson Hybrid). A couple of dealers touted "MSRP".
The one we went with did add a roof rack, carpeted floor mats, and another thing I can't remember. It added up to around $900 on top of MSRP, but it was for things I didn't mind paying for. I also was able to use a Veterans discount that Hyundai offers subtracting $500 for that. I warned the salesman that I'd be bringing a check from Navy Federal, and that they'd be wasting their time trying to finance me. He said that would be no problem.
When we went to the dealer to pick the car up, it was less than a two hour process. I did get an extended warranty, but because I had done my research beforehand I talked them down from $4k to $1,600 for that which we paid for outside of the financing. I could have gotten it for a couple of hundred dollars cheaper online, but I figured this was my goodwill to them for treating us fairly in this crazy market.
Best of luck. It's a crappy time to buy.
