The Jeep Wrangler and Cherokee 4WD both made the Insurance Institute for Highway Safety's list of the most stolen vehicles in the U.S. for 1999-2001 models.

The Acura Integra (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 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 and more than twice the cost of the vehicle with the second highest overall losses.

These are the latest insurance theft loss results published by the Highway Loss Data Institute (HLDI), an affiliate of the Insurance Institute for Highway Safety. HLDI results are the only reported theft results based on the number of insured vehicles. Information on insurance theft losses published by the National Insurance Crime Bureau and CCC Information Services doesn't take into account how many of each vehicle are insured, so the most popular vehicles on the road tend to top these organizations' lists of most-stolen vehicles. In contrast, HLDI identifies vehicles with the worst theft losses by counting the number of theft claims by make and model relative to the number of each make and model insured. Models with the highest losses are identified by calculating both frequency and cost of claims.

Here's the top ten (claims per 1,000 insured vehicles):

Acura Integra (21.7)
Jeep Wrangler (8.5)
Jeep Cherokee (6.6)
Honda Prelude (6.4)
Mitsubishi Mirage (6.2)
