The 2008 is new, thats like 2 months old for me right now, the car for 2 years was a 2000 model, Ford Falcon AU.

I have no idea what old cars you’ve bought that aren’t cheap, but if cheap was the goal you clearly bought the wrong old cars. Outside of my first and current car, all of my cars have been cheap, reliable trash because that’s all I had the money for. I’ve even only had a single car break down, presuming broken down means wont turn on, or wont drive. The Falcon had an issue where it wouldn’t turn off, but arguably not broken down as I drove about 300km like that before the locksmiths replaced the ignition barrel.

Your math is… interesting, and while it actually favours my side, it shouldn’t because you’ve made some presumptions that may be accurate in your country but not mine. $1,920 I figured out is 2 years of fuel which is about right for all the 6cyl cars, Although definitely not my '08, but I didn’t buy that to be cheap. $700 is… I’m presuming you mean that to be car registration but you only account for 5 years of it, which heavily overcounters my slight rounding up for what a year of rego is (670 for a 6cyl, at least currently, hasnt been under 600 since ive had 6cyl cars though). I slightly underestimated with 15k with my math presuming current costs reflect the past decade, i got to about 18k with fuel/rego/services/repairs, however many of my cars have been 4cyls which removes $100-$200/year depending on when I owned them in rego, the 4cyls also definitely cost nowhere near 1k a year in fuel, particularly because I had them when fuel prices were about 40% lower than current. What was an $8 drive is now about $30. I presumed services were all $250, however most of them were under $200, just more recent Mitsubishi Magna and the Ford Falcon were $250. Could lower the total by 2k if you count in selling/scrapping prices, with the Datsun adjusted for what it would’ve scrapped for (~$250) as opposed to the 2.5k I actually got because lucking in to an almost 2k profit after using it as a learner car isn’t realistic for most people.

Car list if your curious, Datsun 180b '74, $700 purchase, used no fuel but also went nowhere, 0-100kph time of ‘one day, maybe’, got pulled over for aggressive acceleration, somehow. Hyundai Excel, $1,300. Ford Laser (AKA Mazda 323 AKA like 4 other cars), $1,000 purchase, never serviced because a friend at the time super totaled it within 6 months of me getting it. Mitsubishi Magna '95, $500. Serviced for $250, was a V5. Not by design but hey it ran. Mitsubishi Magna '00, $700, actually had a full functional 6 cylinders, although a $500 repair bill while knowing the engine had about 20,000kms left on it made me scrap it instead because why spend the value of a car fixing it when it has a problem that’ll cost several times more in the near future. Ford Falcon AU '00, $2k, boring as shit, first car that took actual damage from my driveway, managed to slam the radiator into the ground, which is impressive because that is in theory higher than the bumper and the bumper was untouched from that. Now a Nissan Skyline 370GT, AKA Infiniti G37 in a lot of places, 15k. This car goes significantly slower in my driveway as I suspect a radiator is not a $200 job and I could really do with not breaking it due to poor terrain. Doesn’t really fit the ‘old car on a budget’ theme I’ve been doing most of my life which is why it’s been excluded from the above math, it would heavily skew it towards the more expensive side. Spent like 5k on it in 2 months, brake pads, rotors and tyres combined were like 3k, tank of fuel is $140 instead of $80 or less for previous cars.

The difference is it costs a fraction to rebuild an engine or replace with a lower mileage unit than it does getting a new or refurbished battery pack.

I’m ready for EVs too but the lack of DIY maintenance makes it not make sense.
