I believe leather was the standard interior for US models. If anything other than leather it is likely special order.

What do you mean about the horns? There is a switch with a symbol that looks like an exclamation point, this switches between city and country horn, the horn is dual tone. There are four horns total - two in the grille and two underneath. The two underneath are for the alarm system.
