The actual reason for this is because The Toyota Camry and Honda Accord are the most stolen cars because they're the most popular cars in urban/metro areas. Typical American sedans tend to be easier to steal but have a wider sales range (ie they're sold everywhere - in most studies, the Ford Taurus and Dodge Stratus are nowhere near as popular in urban areas as Camrys and Accords). Since urban/metro areas are where most car thefts occur, this explains part of the Camry and Accord phenomenon. Additionally, the Taurus, Stratus, Malibu, and other domestic products have been around nowhere near as long - 1986, 1995, and 1997, respectively.
On the basis of percentage (which is the statistic that needs to be used in this situation), it tends to be high-end cars stolen more often: BMW 3-class, Audi TT, etc. On this basis, the Camry is relatively average, as would explain its entire existence.
