The term Q-ship originated in WWI when merchant vessels carried hidden armament to attack and sink enemy subs. Today's Nice Price or Crack Pipe Sentra also looks sedate, but hides a turbo 2.5-liter. Would you sink thirteen large for it?
Appearances are not always what they might seem, and looking at yesterday's Mercedes Benz 190E 2.3-16 Cosworth, the layman might not divine its special nature, so subtle are the identifiers. Fortunately this is Jalopnik, not Consumer's Union, and, as predicted by VeeArrrSix, a full 84% of you identified that boiling Benz as unique and anointed it a Nice Price winner- as much for its $5,500 asking price as for its condition. That teutonic sport sedan represented pretty much the best that Mercedes could throw at the market back in the eighties, but time and technology have moved on significantly since then.
