Welcome Berend-Jan, from which part in Holland are you?
I live near the north of Belgium.
I have the privilge to own a Stevens Esprit and a MK1 Elise and the Elise is much cheaper and easier to run. I think you are right about that. Still, it is the Esprit that captures a lot of people their imagination.
An anecdote to illustrate this:
I had my Elise already for about 10 years and driven over 50k kms with it, when I bought my Esprit. I bought my Esprit near the end of the year and so I had only driven it for about 200km and then stored it for the winter. Now almost nobody asked me about my Elise during those years. But during that winter when wating at the bakery, the butcher, the chips shop, etc, people suddenly stepped up to me or my wife and asked whether I still had my Esprit (well in some cases people referred to it as a Fezza, as my Esprit is red). I did not know these people up to then. I was even asked a few times if I would want to make it avalaible for their kids to pictures with it for their holy communion... I got invited to events... etc just to say the Esprit is an even more special car than the Elise and I'm sure the Esprit opened doors that would never have opened for me before. Funny.
