I owned an Exige S for the last 2 1/2 years and only recently sold it due to finalising my mortgage. I used it on a daily basis to get to & from work & never had any problems with it - also used it twice on track (shame i couldn't use it more) and again it wasn't a problem and wasn't that expensive either - getting in & out of one is easy & you easily get used to it - why people claim they can't be used on a daily basis i dont know

In any case TBH if you want decent & honest advice on Lotus ownership, costs involved, etc, then it's probably best reading through posts or asking the question(s) on one or all of these sites

www.seloc.org
www.nyloc.org
www.exiges.com

The first 2 are pretty much the busiest Lotus forums, and Exiges, although not as busy, is dedicated purely to the Exige. All the forums have loads of helpful owners who will give you info on the car, running costs, etc, etc
