Old Vehicle can refer to two different solutions in a crossword puzzle: OMNIBUS (7 letters) and CRATE (5 letters). An OMNIBUS is an old-fashioned public transport vehicle, usually a large bus, that was popular in the 19th century. A CRATE is an old-fashioned car, typically a sedan, that was popular in the early 20th century. Both of these vehicles are now considered vintage and are often sought after by collectors.
