There's a couple of beautiful examples up at the moment:

Was never a fan of the Testarossa particularly and the M has horrific headlights but there's something quintissentially Ferrari and Italian about the 512. It's very special (much more so than a 550 IMO), from the simple cabin and beautiful dials to the exterior lines that look like a really sharp Brioni suit. Looks good value relatively, can't think of much else at the money that provides quite such the wow factor.
