You are at the beginning of a long journey, and the approach you take now and expectations you set will determine the arc of your path. You are young, you are earning money, you are doing a good job saving -- probably better than your friends, right? -- and you have disposable income and start to think, well, I've been working really hard, and I'm making good choices, and I can afford it, so why shouldn't I have some of the bright shiny toys like my friends have?
Do not go down this path. Why? Three reasons, in order from least to most important.
1. Compounding. $10K that you keep invested instead of spending today is worth $80K when you're 65. The money you invest now has far more impact on your future 'stache than any other money you manage to save later.
2. Hedonic adaptation. This is the first big purchase you are making, and it will set the floor for future decisions. Buy a $25K new car now? I guarantee the next one is going to be brand-new and (at least) $30K. Because now that base model is, well, base, and there is some other new thing you want in the next car. And anything like less will feel like settling and be disappointing. You always want to start at the lowest baseline that meets your needs -- and then stay there as long as you can.
3. Using a "thing" as a reward. As others have pointed out, there is no fundamental difference between the new car you want and an older model in good repair; these are standard, relatively generic vehicles that don't go for the bling but last a long time. So why do you want a new one so much? Answer: because it's new, it's shiny, it's pretty. And as I said above, you're working, earning money, making good choices -- so you "deserve" a treat, a splurge, right? And that, right there, is the problem. Yes, you are working hard, earning money, making good choices -- so why is the "reward" for that good behavior blowing unnecessary money on a shiny consumer product that is fundamentally no different than the cheaper used option?
The best thing you can do for yourself at your age is to disconnect the mental link that says "reward"/"treat" = "buy a new consumer good" or "spend money I don't have to." Yes, you are making good decisions, and you DO deserve a reward. But why does that reward have to be a "thing"? Come up with something you'd like to do, that you'd enjoy, that would feel like a reward, that doesn't involve dropping money on stuff. And don't just make that a one-time thing -- work those sorts of things into your life on a continuing basis. You deserve to feel good about what you are doing and deserve to live a life that brings you pleasure and joy on a regular basis. And you don't have to spend a lot of extra money to do so -- in fact, training yourself that "happiness" = "stuff" is the best way to delay finding out what really does make you happy.
Now, I could be completely off-base in all of this. And in the grand scheme of things, a new Honda that you drive for a decade is not exactly a horrible thing to splurge on; many people have done much stupider things. And if you have a specific reason for wanting that particular car that an older version doesn't have, that's fine (I myself have bought a newer-than-intended car because it had active crash avoidance, which was a priority because we have a new driver using it). But you didn't mention anything like that. So before you decide, just put some real thought into why it is you want a "new" car specifically.
