Depends... are we talking purchase price, or current estimated KBB value? I spent $42k on my 2014 truck, and $30k on our 2022 Camry. As a percentage of our net worth...well I'm not telling that figure, but I am also not FIREd yet, we have 3 little kids and having reliable vehicles that we don't have to spend time and money on while they are busy growing was something important to us.
I also went in half on a 2017 2500HD with my DF, that I use for business (Arborist and Tree Care company I run on the side of my IT consulting).
My wife gets paid mileage, so we sort of figure mileage against the cost of the Camry since it basically pays for her to drive. She drives over 30,000 miles a year, and at the federal mileage rate of 65.5 cents * 30,000 miles that's $19,650 a year in mileage reimbursement. I deduct ~10,000 miles for my businesses S-Corp annually so that will be another $6,550 of "deductions" on our tax return, lowering my taxable income a little. If we didn't have the tax write offs we would probably hang onto our cars longer or buy less expensive cars. I am still debating about buying a $60k SS Camaro. For now its a want, not a need so I am having a tough time justifying it. I could pay cash for it without any issues.
Maintenance is pretty low on these vehicles. 8 Oil Changes a year, haven't filled up fluids on my own vehicles in decades since the Oil Change place does it. Buy car washes at a discount at Black Friday time from local car wash place so I get them covered for like $160/yr. Buy Oil changes for a discount on Black Friday from the local repair shop and I think they cost me like $120 for 6 full synthetic oil changes. I buy Wal-Mart's tire rotation package when we replace our tires which is also fairly cheap. Camry is still under warranty as we come up on 20k miles it will be the last "free" oil change and tire rotation. I usually get about 60k to 65k miles out of our tires before I need to replace them. I've had to replace a couple batteries in the past few years, once on my truck, and once on our 2013 Camry we just sold for the newer 2022 Camry. I bought that Camry for 15k used, and sold it for 7k after putting on 170,000 miles. Only thing we had to replace was the battery in our time owning that car, plus 2 sets of tires and some wiper blades.
IF I buy this SS Camaro, which is still up for debate, I would put some work into it (cam, headers, cat back exhaust, cold air intake and upgraded throttle body) so the 60k car might end up costing me 65k as I will do some of the work myself. Will need to pay someone to weld the exhaust on since I am not great at welding.
Anyways long rant. I have to replace the ac condenser in my truck. It went out last summer and I ordered the parts, but haven't had time to tackle it yet.
