Maybe they both were. I mean, if you're going to make the effort to post, why not consider the fact that the OP might be fairly new to the internet, and might not be all that familiar with search engines (yes, I know they're not exactly rocket science, but different people have different levels of knowledge and experience). Why not actually give a useful answer, such as "They're both German manufacturers, competing in the so-called 'luxury' end of the car market, but aside from the German connection, have little in common", and then mention that answers to straightforward questions like this can often more easily be found on search engines, rather than just wasting your own time telling him to look on a search engine, when you could have spent the same amount of time actually giving him an answer to his question.
Yep. Abominable.
