Ok, here goes:

EX LX
gross wt: 4,900 4,550 lbs
front headroom: 37.8 " 38.9 "
front legroom: 42.1 " 42.1 "
cargo cap: 35 cu. ft same
towing cap: 4,500 K same
mpg: 16/20 18/20

I don't think that (stock) there is much, if any difference between the 2.
All measurements are very close.

As far as the interior goes, I believe that the EX can have leather seats, plus some wood trim, which the LX did not have.
There is probably some other differences, but I 'am just not sure.
Any corrections would be appreciated.
