i must go to specsavers as I can't see how the link explains the difference, any way the following is taken from LR's price lists.
Persuit SL suspension yes, GS no
Persuit ACE no, GS yes
Persuit c/control no, GS yes (option diesel)
Thats about it different trim, radio and wheels but they were still 16inch.
I have only taken my info from the price lists of the time 2002 and 2004 but the Persuit is a bit basic not a lot of options availble unlike the Landmark both newer models than the GS, but the GS still had a big option list SLS was an option.
Price, GS 5 seat £27295 Persuit 5 seat £25995
