I think the price is steep...I picked mine up (96 GLE) in 98 for $13k, had 38,000 miles on it. Course my father in law is a used car salesman and hooked me up with it.
Anyways only thing my Max didn't come with was a wing and heated seats. I'm not sure if ABS is an option with the GLE's. Anyways I threw on a wing and pulled some 97 GLE rims off of another Max and put em on mine. I didn't care for the ones that came with mine.
I would say the SE is probably the route you'll want to go if you want to "mod' out the car. You'll have the option for stick, a wing, sport tuned suspension, plus most of the extra's that the GLE comes with.
I don't know what area you're in but if you're around Utah/Las Vegas area then you could probably get hooked up with a Max from my pops in law. He just sold a 2000 GXE for around $15k...
