1987 Lotus Prestige Dura-Ace. Top-of-the-line for 1987 along with the Super Record equipped Lotus Cinelli Supreme.
So far, the rarest of the rare Lotus bikes. I know of none that exist, haven't found any non-factory photos, or even talked with anyone who owned one. Even though the Lotus Cinelli Supreme is scarce, I've found three of them so far.
Some people get all torqued up about supposedly "rare" bikes, of which I've seen dozens or even hundreds. Lotus has many truly rare bikes that so far I only know of a handful that exist, even fewer in original condition.
