That 62C model is beautiful and is very close to the kind of thing I would aim for in my first loco (nice, mid-sized tank engine, perfect era of manufacture), though I'll have to go with black livery for the most part to keep it "global" (nobody else seemed to like coloured trains as much as the British, which is a shame!). Though I'm sure I don't want to know how much it costs!
That east German stuff would be perfect for cars! Thanks for letting me know about the search term - that'll be a big help!
