Time keeps moving, and the cars that plastered your bedroom wall are now classics. RM Sotheby's has put together a collection of about 140 cars from the '80s, '90s, 2000s that represent the best of the era, from Ferraris to Alpine BMWs, Mercedes-Benz AMGs, Jaguars, Porsches, Aston Martins, and the best of '90s Japanese sports cars. The collection will be sold over four auctions in France, the US, and Germany from February to April. A few of the highlights of the collection include a 2006 Ferrari Superamerica; a low-mileage Toyota Supra Turbo, an Acura NSX, and a Mazda RX-7; a Mercedes-Benz 500 SEC AMG 6.0 Wide Body; and a 1994 Porsche 911 Turbo. These modern classics will continue to appreciate in value, making the Youngtimers collection a good opportunity to own some great cars before their prices rise into the stratosphere.
