Too bad, I just sold the BMW 1999 this April.

Regarding "Indeed, it's sad to see that except for Norev and Touring few other OEM release fully opening die-cast models."

Not really, there is so much going on right now, but mostly costly and modern cars.
But LCD, Almost Real, Motorhelix, Kilo Works, even BBR and many obscure (to us) Chinese makers blow out masses of modern sedans, SUVs and supercars.
And PMA returned ro all-open, Kyo too, still they are way below their earlier releases, detail-wise.

It is just easier if one prefers RS6 or Pagani, true.
