I don't know about now...but when I bought mine in '00 there wasn't really much difference between my LE and other '97 wagons. It's really not that
special...so I personally wouldn't pay a bunch more. The Safety Devices roof rack is rather expensive...if a few thousand more than a similar standard wagon with the same miles might be worth it just for that if the other doesn't have it (and you care - I sold the one off of mine).
If you plan to modify it I wouldn't go that route as any premium you pay will for sure disappear once you make changes.
Also I bought a super low mileage (12,000) for an extremely high premium when I got mine and I wouldn't do that again either. I'd look for a very well maintained truck with more miles and a lower price. Once you get a few miles on it that premium is gone.
Of course if you plan to buy it...stick in the garage...never drive it...and wipe it every day with a diaper then by all means...buy #300 from Stewart and enjoy it.
Good luck with whatever you decide...mine was my favorite Rover I've owned before or since.
