CARY, N.C. -

After crunching the numbers on more than 2,000 Volkswagen and Audi models eligible for the VW Dieselgate settlement, online auto marketplace Instamotor found that the average age for these cars is four years, with an average of 95,203 miles on the odometer.

The average buy-back these cars would be eligible for is $21,205, with the average modification they’d be allotted coming in at $6,132, Instamotor said in an analysis shared with Auto Remarketing. (This summer, Instatmotor launched a VW Settlement Calculator to show owners of Dieselgate-affected vehicles what they can expect to receive.)

Of course, those numbers vary by model and state.  For instance, according to Instamotor, the Audi A3 has an average buy-back of $30,220, with an average modification of $7,526.

The Volkswagen Beetle has an average buy-back of $26,599, with the modification at $6,922. The Volkswagen Golf is at $22,062 for the buy-back and $6,200 for the modification.

For the Volkswagen Jetta, the numbers are $19,232 and $5,806, respectively; for the Volkswagen Passat, it’s $24,662 and $6,612.

And those numbers vary by state.

In New Jersey — home to Volkswagen’s U.S. headquarters —  the buy-back average is $20,538 with the modification coming in at $5,959, according to Instamotor.

However, in New Mexico, the buy-back average is $15,950 and the modification is at $5,312.

A scan of Instamotor’s infographic shows the state with the highest average buy-back to be South Dakota ($30,407), the only state to crack $30,000. South Dakota also had the highest average modification at $7,557.

A blog post on the Instamotor website from head of market intelligence and communications Kristen Andersson shares an infographic on how, exactly, those numbers are different in each state.
