I think the answer is mostly based upon future demand, compared to what Lotus produces. So the usual "supply and demand" issue. Then there are many factors that come into play which impact demand, such as what else is out there for sport car options buyers can choose from (ie. manual transmission? weight? looks? price of the competitor models? electric becoming more popular if electrical supply becomes for plentiful-ie. more nuclear reactors come on stream-and battery quality/longevity improves). If Lotus comes out with an Emira with more HP, that could negatively affect the existing Emira's resale value. What emira_eli says, may or may not hold true for the Emira, since the Emira appeals to a broader base, with its more "daily driver" characteristics as opposed to being so track-focused (with track use, appealing to a smaller and more select group), compared to those past Lotus models. And if Lotus produces a more reliable product, to overcome the oft-seen stigma on Lotus vehicles, that will also have a big effect on buyer perception. Only time will tell, how this all plays out. What do you see in YOUR crystal ball?
That said, we're now seeing new Emiras sitting at dealerships for sale and more used Emiras hitting the market place. I suspect with this increased supply and if production remains steady, the price of used Emiras will dip in the short-term...even after a modest price increase for the new ones. Then if Emira owner's testimonials that their Emiras have been problem-free (like mine) spread the word, plus more "I love my Emira handling" videos surface on YouTube, the prices might bounce back...and sooner than "the first few years" indicted by emira_eli.
Finally and as with any sport car, the economic conditions will dictate pricing. If there's a ++ big downturn, most sport car prices will take a big hit.
