I too experienced the "cheap and poorly designed horn button break off problem" in my '94 855T (62,000 miles, Honest!) Anyway, the dealer wanted $500.00 to fix it. Uh huh, says I. .I bought a small springed push button at the local Rradio Shack (about $5.00) and had my mechanic install it on the dash next to the steering column. He just fished the horn wire out of the wiring harness on the steering column. Works fine. Don't use my horn that often anyway.
