A friend of mine recently bought a brand new Corsa Griffin, and it's like they completely forgot to finish designing the interior in the back: the doorcards are solid plastic, no cloth trim at all; and the back seats don't split-fold!!
Corsa is an old beast though, and they are cutting costs pre-replacement.
The 3 was something else, tbf one I was in is a 25k car but padded stitched leather on all the doors, dash, seats. Proper milled metal door handles, speaker grilles and knobs. Even the gearknob was a metal ball with padded leather trim.
Also no drop in quality from front to back..kinda like an Audi A3 feel but less obvious penny pinching.
Was rather disappointed to get back into mine much as I love it this is just a different thing altogether.
