interesting - this covers the yr 2000 colorado like mine
auto mpg 23.9 combined - makes me feel better!
also lists the FX - that mine is, as having aircon
"Air conditioning and anti-lock brakes now standard on all models"
it says 8-seats though, mine only came with 2 seats in the boot - which i removed
maybe there was a 3rd middle lap-belt, i will have to look in attic sometime to check
