2002 - 2003 XC how can I tell which AWD sys?
 

I've been reading here and other places about the mechanical drive system being very touchy and the change over to electronic was 2002/2003.

I'm looking at a car tomorow and I was wondering how I can tell which system is in the car?
The dealer says it's a 2003 car but it was registered at the end of 2002 so it says 2002 on the info.

Thanks in advance,
Alex JB.
