I’m fairly similar to @Crafter_Man. I have a 2004 Buick which is my daily driver, a 2002 Jeep that is my bad weather vehicle, and a 1995 F350 which I use to haul stuff around and also functions as a backup in case one of my other vehicles has a problem. I also generally do all of my own maintenance and repair work.
I had to put new tires on the Buick last year. I have also had to replace the glow plug relay on the F350 twice since I’ve had the truck. I haven’t had to do anything with the Jeep yet, but then I just bought it last year.
I also have a 1953 MG TD, a 1968 VW Beetle, and a 1926 Ford Model T. These obviously aren’t daily drivers. Plus I have an old Harley-Davidson motorcycle.
I probably spend about $200 to $500 per year in parts for all of my daily drivers combined. Some years will be less than that, but then in some years I need to get new tires for one of them.
It’s probably about $200 to $500 per year on parts for the antique cars as well. They don’t get driven anywhere near as much, but they do tend to break more often. This year, both the MG and the VW had broken fuel pumps, and the Model T starter bendix broke (to be fair, it’s a 98 year old part). The VW and the Model T are very easy to get parts for. The MG, not so much.
My daily drivers typically cost between $2000 and $5000, and I keep them for about 10 to 15 years. For example, before the Buick, I had a 1980s era Cadillac, which I had for about 15 years. Over that time, I had to replace the battery due to a sticky relay killing it, and I had to replace brake cylinders and brake lines, and that was about it. The power window mechanism broke and I couldn’t find a replacement part for that, so that part stayed broken until the car died. I paid $5k for the car, and total parts cost over that 15 year period was probably about $1500, including tires and oil changes.
Another example is the old Dodge pickup I had at the same time. I paid $1500 for it. I had to do a lot more work on it, including replacing the radiator, replacing most of the exhaust system (twice), replacing the catalytic converter, and replacing the EGR valve. There’s a bit of a funny story involving this truck, but in the end I probably had about $2000 into it by the time it died.
The long and short of it is that most of my daily drivers have lasted about 10 years, with a total cost of less than $5k, except for the Cadillac which was closer to $7k. I bought one new car when I got out of college, and it was a very cheap car. I’ve bought all used cars since then and, with that one exception (which I paid off in about a year), I’ve never had a car payment.
