Well, if you want a good deal on an MSM...
... now might be the time to buy. Mazda has confirmed that no more NB Miatas will ever be built, due to the fire at the factory in Japan. Instead, once the factory is repaired, they will be ramping up production of the other models (RX-8, Mazda3) that were built at that factory to comply with demand. Instead of rebuilding to produce the NB for a month or two before NC production starts, they've decided to forget it altogether.
So, if you want a new NB, don't waste time, 'cause what you see on dealer lots is all you're going to get. Ever.
In a way, it's kinda sad. :( I hope the NC lives up to all of the hype surrounding it.
