I really don't know at the moment... but certainly starting to think ahead about things. Possibly one of the following in order of preference:
New 2008/2009 BMW Z4
Audi TT
Boxster or Caymen
Some sort of 3 series (either an efficient diesel or a big polluting petrol)
Thinking about changing late 2008 or early 2009... depends how money goes as I'm contemplating paying off my mortgage this year
