I guess it could also have the opposite effect... some cars have been made so often, that nobody needs another copy - Jaguar E-type, Mini (including New Mini), Beetle (including New Beetle), Corvette (most types), Porsche 911 are probably the most obvious street cars. In other categories it could be the Thames Trader, Routemaster bus, VW Samba.
Because of the nature of the Atlas collections, where people can't pick and choose, one looks at what's in store, and if that list includes a whole bunch of models you don't really care for, then you won't subscribe.
On the other hand, like you say: if there are lots of highly wanted models promised, then it's a big plus.
The solution sounds simple, but I guess it's not, or it would have been adopted long ago: don't flog the dead horses! There is no written rule that every street car series must include a Mini, a Beetle, a Porsche 911 and a Jag E-type! Yes, we do know they're classic and that they belong to any line-up of classic cars, but we already have them!
The Atlas models are (mostly) very good, but let's be honest: their cars are not 'better than anything else you've ever seen', which would justify the inclusion of the 'dead horse brigade'.
Basically it's a matter of "glass half full" or "glass half empty": is it "I'll get a lot of models that I really want" or "I'll get a lot of models that I'm not interested in" - I guess Atlas see the glass as half empty
