The package is provided by GMAC Financial Services UK and was initially available for one month during the summer.
Barry Willson, GMAC brand manager, said: “More than a third of all Chevrolet customers have bought their car using ‘3 and Easy’ since it was launched on July 1.
“There is nothing similar available anywhere else in the marketplace and the overwhelming response we have received from car buyers has led to the offer being extended again.”
The ‘3 and Easy’ purchase plan requires buyers to pay one third of the vehicle’s cost up front, followed by one third after 12 months and the final third after 24 months. There is no interest or fees, customers pay only the original list price and will own the vehicle outright at the end of the plan.
The deal will be available in all UK Chevrolet dealerships and will run until December 31.
