I have to agree with Doug here. You have 20 years of brand recognition for Optima and you just toss it out? FACEPALM!
Could you imagine Toyota building up a name with the brand recognition of Camry and then saying, "NAH! We we just rename it the T5!" This is why Toyota has been on top for so long. They understand their customers and ultimately the market better than virtually any car manufacturer other than maybe Honda.
Think about the reaction to the name change though…..
Toyota: Introducing the NEW T5!
Toyota Customers: Is that new Terminator model?
