Vauxhall expects over 50,000 drivers to take part in the scheme in the UK, which will allow customers to take a Corsa, Meriva, Tigra, Astra, Astra Sport Hatch, Zafira or Vectra for a full 72 hour period.
Participating Vauxhall retailers will be making nearly 2,000 cars available from the beginning of April until the end of June to cater for the extra demand.
Vauxhall’s marketing director Andy Gilson said: "We are truly confident in our range of cars, and want people to experience them in everyday situations. Last year, the programme attracted 48,000 customers to our showrooms and our research showed that a massive 71% of test drivers were more positive about Vauxhall as a result. We want drivers to see how one of our models will fit into their lives."
The three day test drive will run until June.
