Comerica Bank recently issued a report on the costs of purchasing a new vehicle, and while the affordability index has remained relatively unchanged, it still takes 22 weeks’ wages to purchase a new car, compared to lower prices for used cars in New Jersey.

The financial institution said that the numbers are actually slightly higher this quarter, as dealers and automakers restrict some of the affordable lending options initiated during the financial downturn to boost sales.

“Reflecting the partial normalization of credit markets, the average rate paid on a car loan at finance companies was only 3.45 percent last quarter, the lowest level seen in five years,” noted Dana Johnson, Comerica Bank chief economist.

However, incentives like attractive financing and the Cash for Clunkers program are unlikely to last, as Congress and the Obama administration are looking to put Chrysler and General Motors onto a comfortable profit margin with limited incentives to buyers before selling the public’s stake in both companies.

Resistance from Republican lawmakers, as well as some Democrats and environmentalists, could also limit future funding for the Cash for Clunkers program, making used cars in New Jersey a more affordable option for some buyers.
