The ford transit custom PHEV costs £4500 to replace the timing belt. Access issues mean dropping the hybrid battery and parts of the sub frame. Compare with the mk8 transit, i've done the wet belt myself on that and it requires no special tools (well, i bought a specific crank pulley puller for £20) and can be done in a day on the driveway. I believe in some markets the replacement schedule is down to 6 years for the new phev due to all the wet belt failures on older models.
So far my favourite brand to work on has been Mazda, the engineering is very thoughtfully done with consideration for repairs.
I hear a lot of praise for toyota but it's from people who haven't worked on a car themselves rather than mechanics and they must be talking about toyotas from a bygone era because i'm not impressed with a 2019 corolla engineering at all, specifically various parts of the electrical system. I believe that was the most popular car in the world at that time.
Tesla is remarkably well done. Simplicity is under rated. So much so i bought one with the intention to keep for a looooong time.
I've heard this from mechanics already 15+ years ago. Mazda seem to still have this reputation.
I wish there were more repairability scores for cars.
Another source of good recommendations could be insurance companies. Cars with low reliability or very expensive fixes probably need more expensive insurance. But I don't know if this data is public or if you can tell apart the reliability from the repair cost.
I must say that I've been impressed with Dacia. Even the build quality is excellent - on par or beating VW. I've driven on Romanian roads so I can see why they would prioritize such high build quality.
