i've also got an 02' coach edition and it's awesome...very reliable, decent power, interior is GORGEOUS...and best of all it isn't Huge like many other luxury SUVs. I say go for it.
btw the coach edition was a 'package' offered that included things like special wood grain trim(birds eye maple), Honeycomb grille, better leather interior, and little things here and there...and of course the coach edition badges.
