Just an opinion. All decisions regarding your personal life don’t have to be 100% business unless you choose them to be. If you want to replace one or both of your cars with brand new cars and you have the means to do it, it’s arguably not the best business decision but it may still be the best decision. For example, how many people can legitimately argue it makes business sense to buy a pleasure boat or motorcycle or camper or a lot of other depreciating assets that don’t generate income? Doesn’t mean it’s always a bad decision to buy one.
To me, vehicles are a tool to accomplish a job. Nothing more, nothing less. I plan to keep my 8 year old 95,000 mile work truck Tundra until it becomes unreliable.
My wife’s car we trade and get her a brand new one every 2 to 4 years while the trade value is still good. From a strictly business/financial standpoint, that’s not the best plan, IMO. She left home when she started working full time at age 15 while still finishing high school. I was in college working part time when we got married (she was 19, I was 22). We had no outside financial assistance, her from age 15 and me from age 20. To put it mildly, finances were tight. If I want to keep her in a newer car now, I will admit it’s not the most cost effective plan and still do it without hesitation or apology.
Not financing vehicles may also not be the best business decision depending on specifics of the deal. Business debt I can deal with when it makes sense. I HATE personal debt. That’s a personal bias not much different from my disdain for lima beans. Doesn’t matter what logic is applied, I still hate limas and personal debt.
If you find a prior model year still on the lot when the new model year comes out, you may pick up a good deal on a new car if you’re flexible. Best deal I ever got in a new vehicle was a Nissan Frontier with a 6 speed manual still on the lot 3 months after the new year model was out. Went looking for a black 2WD 2door automatic. After 6 hours of negotiating, left with a white 4 door 4WD manual for $3k under NADA retail for a used one with 15,000 miles because nobody other than me would take a manual trans. Good thing I got the manual, the automatics those years had all manner of problems.
