You shouldn’t “invest” in depreciating assets.When I sold Porsche years ago in undergrad they trained us to point out that a Porsche was an investment since it depreciated less than any other new car. I was always amazed how many people wanted to believe it. And Similar to @eatSleepWoof said I bought my 1 year old LX for $20k off a new one.
But you do need to get around, tell time, make phone calls, etc. It makes sense to get the best quality/least depreciation that you can afford that fits your needs
Buy once, cry once they say.
