Do you really think Lotus's crystal ball can see THAT far into the future!!!! hahhaa
but yes, the "current" Elise will basically only have a 2 year run, and then it would either be modified, or dropped all together. I am sure lotus would like to modify it to a world car, AND have the 2+2, and the Esprit replacement, but is lotus financially capable of a 3 car line up? thats the big mystery that they probably don't even know.
that car you saw isnt the elise replacement, it is the replacement for the M250, which was never produced...its priced between Elise and Esprit...hethel has been planning that model for yrs...the Esprit replacement look pretty nice...but for anything over 100K, I would never buy a Lotus...I would get me a F430!
