My best mate has a 06 Elise 111S sitting on Nitron suspension and AD08R with which I've been lucky to take on track days and use on extended loans when I fly back to Aus for a visit. They are an amazing car but definitely on the more extreme end as a road car. On the open road it is fantastic, on a busy city road you spend a lot of time being nervous about other drivers as you sit below their window line.
Yeah I think anything outside being used as a weekend,quick blast sort of car might not be ideal for everyday use.
Most people want that feeling that an Elise provides but they also want some semblance of ease of use and a bit of comfort etc.
