FWIW I called London this morning and the consensus was Vauxhall's are garbage. One guy said in a thick accent that he had a Packard that was more reliable than a Vauxhall. I laughed. With that being said, these cars have the SAAB 2.0 and Aisin 8. I think they are good as long as they don't fall apart or have electrical issues.
Saab never offered VVT or direct injection as the GM Ecotec 2.0T has been flawless since 2006 unlike some VAG engines.
