1982 Aston Martin Lagonda Stretched Limousine MkII
The most notorious car that came out of Miami Vice was the Lagonda Stretched Limousine MkII. Aston Martin was prominent in the 1980s as its cars were extremely fast and luxurious. The company was the pinnacle of society in the automotive world, and the Lagonda was already a big car before it was converted into a limousine (via IMCDB).
What made the Lagonda Stretched Limousine MkII special was how different it was compared to anything else on the market at the time. Sure, you had limousines, but they were nothing like the Lagonda. This was just one of the hundreds of cars specially picked for the Miami Vice TV series.
