New Car Purchase?

Need some advice if I'm ready to buy a new car

I'm 35 and been driving a junker I bought 6 years ago for $3,000. It still runs and drives fine but I'm finally at the point where I want to upgrade.

We own a home, I have no debt. And I have about $100K in retirement.

I make about 80K per year.

I'm looking at buying a 2024 Hyundai venue for about $18K.

I've always wanted to stay away from debt, I currently have about $15K in cash and should be landing a 5-10K bonus at the end of the year

Was think of using 10K I can put as a downpayment and finance the other $8K. I honestly think I could pay it off in a year after my bonus comes through. Or should I just wait and save up for another 6-8 months and buy it in cash.

Any advice or encouragement would be appreciated.

Thank you!
