Shaman,
I live in Chicago as well ( suburbs ), and I traded in my 2004 X-Type for a 1999 Boxster in April :

There is not one day that has gone by that I wished I had kept the Jaguar
You will LOVE the Boxster !
As soon as it warms up, drop the top and take a cruise down Michigan Ave or LSD.
Life does NOT get much better
Good luck...
Nick
