Lamborghini Countach.
What to Check Before Buying.

The Lamborghini Countach defined the supercar era from 1974 to 1990, with its wedge-shaped body and scissor doors becoming automotive icons. Most examples in the UK are now cherished collector pieces, kept in climate-controlled storage and used sparingly. Buyers should expect complex maintenance requirements, six-figure restoration costs for neglected examples, and the need for specialist mechanics familiar with carburetted V12 engines and period Italian electrics.
