Two friends will embark on a 2,000-mile journey (3,220km) from Birmingham, through Europe to Benidorm in an "old banger" in memory of their friend who passed away.
Simon Lewis, 57, from Gloucester, and Kevin Paskin, 53, from Worcester, are taking part in Benidorm Bangers charity road trip rally.
On Sunday, they will set off in a car they bought for £390, driving through five countries in the hope of raising money in memory of their good friend Terry Brazier.
Mr Paskin said: "Terry would have loved it – he was involved in planning the trip from the beginning. His passing was unexpected."
Terry Brazier died from a heart attack aged 59 in November.
"He was a very good friend," said Mr Lewis. "We both knew him through work, but also personally as well. We had holidays together."
