If you think your Acura Integra is fast and gorgeous, you aren't alone. The car model was one of the most-stolen last year most likely the target of street racers.

One out of every 200 registered 1999 Acura Integras was stolen last year, said Chicago-based CCC Information Services Inc., an insurance industry tracker of theft and vehicle damage. This makes the Acura Integra the most stolen car in America. Acura Integras from model years 1995 through 1998 took four of the other top 9 positions on the list. The 1994, 2000 and 2001 Acura models also make the top 20 list. The list ranks vehicles by the percentage of registered vehicles stolen, rather than by gross number of thefts.

Jeanene O'Brien, CCC's director of marketing services, said an upsurge in street racing may be responsible for the appearance of the Acura Integras and other fast cars on the list. We can never say for sure why a car's stolen, but we can look at the data and make some interesting assumptions," O'Brien said. She also said the Acura Integra, which was replaced by the RSX in the 2002 model year, also may be targeted for its parts. Acura is Honda Motor Co.'s luxury brand, and the Acura Integras engine can fit into other Hondas, for example.

Acura spokesman Mike Spencer said Acura was aware of the theft problem and made several changes to the Acura Integras during its lifetime, including adding more secure locks and immobilizer systems and installing door panels that were harder for thieves to break into. "Unfortunately, if somebody really wants to steal your car, they're going to steal it," Spencer said. "That's pretty hard to avoid."

The average age of a stolen vehicle in 2004 was 6.6 years, down slightly from 2003. The average age of all registered vehicles on the road in 2004 was 7.9 years. Vehicles from the 1997 model year were most susceptible to theft last year, followed by model years 1996, 1999, 1995 and 1998. Acura was the most-stolen brand, followed by Hummer, Land Rover, Daewoo and Honda. The Acura  (2- and 4-door) had the most frequent theft claims among 1999-2001 models. Its claim frequency was more than 8 times the average for all cars and more than 2-1/2 times higher than the frequency for the vehicle with the second highest theft claim frequency, the Jeep Wrangler. Largely because of the Acura Integra's very high rate of claims, this car also had the greatest overall theft losses, as measured by the average cost of claims per insured vehicle  about 14 times the average.
