1987 Lamborghini Countach 5000 Quattrovalvole – $400,000
The Countach is among the most widely desired supercars of all. Indeed, many consider it to be the picture-perfect example of everything a supercar should be. Loud, highly-priced, and not a practical vehicle at all to own, this is the fastest Countach, thanks to a mightly V12 engine that offered up to 455bhp. However, it also offered a range of driving improvements, such as improved handling. It’s also famous for beating the Ferrari Testarossa in terms of power at the time of its reveal, something that was considered quite the shock at the 1985 Geneva Show.
