I believe they built B5's in 2010 for 2 months. Unfortunately I really thought being 1 of 153 was pretty cool, until Dodge said they were making them again in 2010. I believe they made the 2010's because all the people who ordered them in 2009 didn't receive them because the plants closed down.
So 1 of 153 in 2009 is true, but 1 of ? overall seems to be unknown. On top of that, I am unsure if the car has any additional value at this point over any other color. I mean it's the same car, just a different color. My B5 is beautiful, but the 392 has my eye now. It's doubtful I will be handing on to my B5 for much longer.
