This is a 1970 Plymouth Roadrunner Superbird.

With its 425hp 440ci hemi motor, this sport bird could reach a top speed of
300 km/h. It was seen in many nascar races at its time.

The Roadrunner was not fragile. Unlike some sports cars (such as the Corvette),
it was built for serious street work, which might be why so many have survived.
The Roadrunner was reportedly a favorite of moonshiners, faster than almost 
any police car and tough enough to take practically any bump. It also had good 
ground clearance. It had very good aerodynamics, which had a drag coefficient 
many of todays models would envy. 

In case you were wondering, yes, the Roadrunner was based on the cartoon. 
It even had a horn that went 'beep beep'! The steering wheel had a little Roadrunner,
and the air cleaner had a cartoon with the logo "Coyote Duster."  
The Superbird went one further, putting a huge Roadrunner (with helmet) onto 
its massive rear spoiler (which had plenty of room for it).
The spoiler gave a very good stability at speeds over 200 km/h 

In 1970 A roadrunner cost about $3.900. Today the same car in good shape cost
about $200.000
