debating buying used model 3

hello! i recently got a new job that pays decent and needs me to drive a lot. i need a newer car that is more comfortable for long drives and is a better first impression for work as i will be driving to clients homes I believe i will work this job for a year and then move and sell whatever car i get. i will get paid for miles that i drive as well.

my friend suggested getting a used model 3. it sounds so appealing. i will paid for driving since i wont be spending money on gas. the plan is to finance and then just sell it in a year when i move and not spend much money. i raised a lot of concerns like the value dropping and not being able to sell it for a price close to what i paid, crashing or denting it and making the value go down, a new car getting released and not being able to sell it, etc.

the alternative is buying some random used car for like 8k. that’s also risking something going wrong with it but it wouldn’t be that big of a loss

my big fear is that im making a 25k bet and if it goes wrong that is not money that i would be comfortable losing. but he said theres no possible scenario that i would lose that much.

does anyone have experience buying and then selling? any scenarios you can think of that it would go wrong? does it sound reasonable?

thanks!!! it’s my first big girl job and i am very excited but this decision is stressing me a bit.
