Any professional panel beaters / mechanics that can advise please:
as to which brands or new models offer ease of reparability.

After seeing new cars / trucks apart, it seams to me most are require excessive effort and labour time to
remove disassemble - parts off for repair.

However they all seemed to be built for ease of assembly .... (appears putting them back together is fairly quick process)

Are there any newish releases that are a pleasure to work on - designed well for repairs if needed compared to the average poor assembly only design?

I think Mercedes started the trend way back when for example the front bumper had to be removed to replace a headlamp.
People were unhappy happy about it back then, but now that looks like a good design compared to the near impossible plastic tab click hold together the modern stuff.
