Hi!
I joined the forum to answer that question
Schuco moved to Bangladesh based factory, hence the much lower production cost than China. As with transfer of any manufacturing facility they started with products known to them, so they rereleased models using molds that were already in use in China. That is why recently there were so many rereleases of old classics (T1, 911, 934, targas, 356, Pagoda etc.). They all had the same details as old releases sometimes only missing chrome plating or leather belts replaced with plastic etc. Unfortunately quality of assembly (as with any new plant) was... not the best (to say the least), therefore do not be surprised if your new Schuco models sometimes need to have some parts... reassembled. Lately I got T1 Samba that I had to reattach 2 seats, one door hinge was unpainted and panel gaps were so huge I could see future through them. That being said, Schuco is the only brand that recently decreased prices and they did it dramatically (sometimes up to 30% compared to the previous releases).
as for the completely new models (some unimogs, upcoming Merc truck, Gullwing) they usually are simplified (I’m assuming both due to inexperience of the new plant and obviously increasing prices of every material). It is especially visible with L322 truck, old release was absolutely jaw dropping model, one of the best 1:18 models I’ve seen, easily comparable to CMC trucks. New one has only doors opening + plastic cargo cover and closed bonnet (and ugly plastic grill).
that being said, I am all for old molds rereleased even if sometimes I need to reassemble something but get f. eg VW T4 for 105€ instead of 140€. Especially that quality of Bagladeshi plant products will surely increase with time.
Hope that helps!
