14” MacBook Pro M1 Max 64gb 4tb -> 16” MacBook Pro M4 Max 48gb 1tb

Will I see a big improvement if I upgrade a M1 to M4? I know I’d see upgrades with video processing etc, but what about for normal day to day use? Much better battery life?

I found the M4 Max for $2500 open box on Amazon. I’m thinking I could sell the M1 Max for $1200-1500?

Should I finally upgrade or HODL?

Yes
M1 Max, M2 Max, M4 Max compared - how high-end Apple Silicon has evolved

The M4 Max boasts nearly double the multi-core performance of the M1 Max and a significant 60% increase over the M2 Max, marking the biggest generational leap in Apple's high-end Mac chips.

I’m thinking I could sell the M1 Max for $1200-1500?

I think your price will be closer to 1,000 then it is to 1,500. Higher spec'd macs do not hold the same value as base models because there's limited demand.

Refurbs are closer to 1,500, if apple is selling them, but they carry a warrenty and are backed by apple, so they can charge more.

Should I finally upgrade or HODL?

Only you can make that decision, but you're in a bad spot in a sense with the M5 Max being released in a few months.
Food for thought:

• Current 16" M4 Max MBPs with 64GB of ram, 1TB storage, 14/32 cpu/gpu cores is 4500 dollars. Is this laptop "renewed" or open box?
• What about a Mac Studio, you almost surely can get a brand new studio for what you can get that open box one from amazon
• Waiting for the M5? Will you have buyers remorse once the M5 Pro comes out?
