Well - I could give you the Robin Reliant - totally accurate name. It would constantly be robin you of fuel and oil, and you could rely on it to break down if there was any sort of damp at all!
Nah though - '56 Mercedes 2 seater, gull wing. I saw one at a fair in 1962. Owner sat me in it, started her up, and you couldn't hear a thing, the engine was that quiet. Been in love ever since, just never had the spare price of a couple of houses to buy one.
