What if the manufacturer decided to offer a third generation of their small coupe/roadster?

Well then it could look similar to this rendering, created by KleberSilva, which sees the Opel Tigra adopt a modern makeover, inspired by the brand's rival to the likes of the Fiat 500, the Adam, albeit on a slightly smaller scale.

Whether or not bringing back the Opel Tigra from the dead and making it look similar to the latest vehicles made by company serves it right is a good enough question, coming up with an answer is pretty much pointless, as the chances of seeing a new interpretation of the small car in the coming years are close to zero.
