A £1500 car is £1500 because it's expected you'll need to replace the engine or transmission pretty soon. That can be up to a £4000 job (£2500 on the low end).

And, as it turns out, a brand new 50kWh battery costs around £4000 to manufacture. Used will be cheaper.

With most modern ICE cars everything but the transmission and the engine will fail before those two go out. Also: I don't think that's the usual case. Plenty of sub 2k cars that will happily keep driving for years (I've had 3 such cars). ~700 mark is where you start seeing 300k mile "finish-them-off"-type cars.

Really not true at all. Care to share your sources for this claim? Anecdotally, I've (plus friend and family) owned plenty of beater cars in that ballpark price, and none had failures needing to replace engine or transmission. Most of their faults came in the electronics (sensors, actuators, fuse box, wire harness) plus suspension, body rust, etc basically the same parts EVs also have.

Meanwhile, if you look up 'EV clinic' postings online, you'll see they find plenty of design failures with European and Korean EVs that are basically ticking timebombs(sometimes literally, hello Stellantis) where electric motors, inverters or battery packs are guarantee to fail in a short timeframe due to various design faults that were entirely preventable. Most common faults with poor EV designs I saw, seem to be the seal of the electric motor stator cooling which fails quickly leading coolant to flood the motor rotor killing it, needing a rebuild.

From what I gather from their analysis', the crux of this issue seems to be that some modern EVs, especially those less premium ones, are cost cut to the extreme in a race to the bottom to maintain shareholder value, both at manufacturing but also at design phase, leading to cut corners everywhere and such issues being a common occurrence and manifesting en-masse after their warranty runs out. From their analysis, IIRC Tesla's powertrains seem to be some of the most reliable and well designed, with the likes of Audi, VW, BMW, Mercedes being less so and Stellantis being trash tier.

Meanwhile, plenty of older ICEs are largely immune form such massive reliability faults, because they benefited from decades of industrial design and development experience done in a past era where race to the bottom cost cutting and planned obsolescence weren't yet a thing. So I wouldn't be surprised when an older 1500$ ICE car will last longer than a 1500$ EV.
