3 cars, each with a unique love story. Which appreciated most?

Love can play a role in a car's appreciation value

It's an odd question: Does love affect the value of cars?

On a recent episode of CNBC's "Jay Leno's Garage," Jay meets with appraiser Donald Osborne to find out the answer. In the above video, watch as they evaluate three cars to see how each one's individual love story may have impacted its overall appreciation in value.

1. 1954 Austin-Healey 100-4

The first car is a 1954 Austin-Healey 100-4, and its love story is about family. This particular car had only one owner, who used it to take his kids to school. Today you would never see young children up front with dad in a two-seat convertible. But back then it was more acceptable.

The car was a part of their family history. It was also just about the coolest way to get to school in the morning: pulling up in a red roadster with a beautiful fold-down windshield.

This "baby Jag," as Jay calls it, originally sold for about $2,900. It was a lot of money, but as the model number suggests, it was guaranteed to go 100 miles per hour. Buckle up, children.

2. 1966 Ford Mustang

Which of these three classic cars appreciated best over five years.

The next car is a 1966 Ford Mustang, and its love story is about drivers in the United States. Americans fell hard for this car. In fact, during its first year of production, Ford sold 417,000 Mustangs. This particular one originally retailed for about $2,600, and it is highlighted by its interior seat coverings, which depict running ponies.

The car being looked at by Jay and Donald also comes with a rally-pac, an additional tachometer and clock that Ford sometimes included during the 1960s.

3. 1957 Alfa Romeo Giulietta Spider

Finally, we turn to Shakespeare for a 1957 Alfa Romeo Giulietta Spider. Giullietta is Italian for Juliet, as in "Romeo and Juliet." That's the kind of love we're talking about.

This particular car, which originally sold for about $3,100, came out at a time when Alfa Romeo was in the midst of heavy production. For a long time, the brand had been quite limited and only focused on very wealthy customers. But to stay afloat financially in the 1950s, it went for wider appeal and mass production.

So which of these love stories has the greatest effect on the car's appreciation? Watch the video to find out.
