I think the new Defender is a lovely looking vehicle, which probably has a similar complement of bells n whistles to the DS.
I bet it's the same as the FL2 Facelift, which isn't difficult iirc.
I have an IID, but it's abilities on the FL2/DS/Evoque are limited.
I've just ordered a Mongoose cable which comes with SDD (probably a clone), for in depth diagnostic stuff, although I'll need a decent laptop running XP Pro Service Pack 3, in order for it to work.
I've plenty of current options for the FL2 which are the IID, WOW/Delphi, and Icarsoft I930.
If you are visiting at some point, you're welcome to try what I have.
