I suspect Otto are increasingly using Solido as the source for more 'conventional' releases.
More narrow focused subjects will be in resin, probably in reduced production numbers.
And as for GTS? Who knows where that's headed.
I'm quite annoyed by all the b versions coming out, also in big numbers. All the numbers of their upcoming releases are 2500-4000 pieces per model and sometimes the b model also has the same amount of pieces as the regular one. It used to be way less, it's not as exclusive as it used to once. The least they could do is to make a bigger difference in looks between the regular models and the b versions.
The Opel looks good, although there are more interesting drivers who competed in these cars - for me at least.
Including no less than Ford WRC car builder Malcolm Wilson.
Sometimes entered as a Vauxhall and other times as an Opel.
And Russell Brooks in an Andrews car.
