Rank 21 in F1 Heritage Collector documents Alain Prost as an active-suspension specimen — the Williams FW15C arrived in 1993 as the most sophisticated Formula One car yet built: hydraulically controlled ride height, traction control, ABS, and Renault V10 power managed by a driver who had already won with McLaren and Ferrari. Prost's fourth title — taken at Adelaide after announcing his retirement — closed the Senna rivalry arc and validated Frank Williams' engineering partnership with Newey and Head. The plate treats FW15C Rothmans livery, French tricolour accents, and Williams W crest as catalog facts on warm cream paper — exactly as a heritage driver layout demands before you open the Professor's McLaren turbo years and the Senna wars that defined an era.
