Adam and Corsa models will be subject to a £500 discount to consumers booking a test drive during August and September.
The Test Drive programme will take place at Vauxhall retailers nationwide and applies to selected Adam or Corsa models purchased and registered between now and September 30.
Leon Caruso, Vauxhall’s retail sales director, said: “Vauxhall’s Test Drive Programme is a great opportunity for customers to not only experience the new Corsa or Adam, but to also walk out knowing they have secured a great deal.
“It’s a good opportunity for customers to make a saving on their new car while making the most of a number of great finance offers too.”
A spokesman for Vauxhall told AM: “The price increase in July was the result of exchange rate decline increasing our costs. It was a straightforward rise – the dealer margin is a percentage of list price.”
