Public insight about a new car!

I'd like some non biased opinons on my plan here. I'm looking at a vehicle in the price range of $55,000 with all fees, taxes and services included. However at the moment, I only make $40,000/yr. The good news is that 1 year from now I am guarenteed to make over $110,000/yr more than I do now.

I know I know... the reasonable thing to do is wait 1 year from now and get the car.

Thing is... I wan't it ASAP (FOMO)

I guess what I'm asking here is are there any REAL downsides to get a super long term loan (72 or 84 mo) payments so that I can have lower monthly payments, and then in a year from now make super large payments for a very very early payoff?

I have no other debts, responsibilities or rent.
