Of course I would do that. Pretty much any rational investor would do so.
You obviously have no idea how big Volkswagen is, and are totally into Tesla hype. No real businessman would buy Tesla before Volkswagen for same money. Actually I don't think anyone sane who knows how business are actually run(and not just studied it without real life experience) would buy Tesla for half before Volkswagen for full price, because it's totally dependable on single next car and crazyman behind their keyboard doing shady things on stock market.
