Charlie Wise, 23, had just purchased the Volkswagen Golf when she discovered the slippery serpent curled up on a stack of towels.
The childminder from Thatcham, Berkshire, and her 25-year-old husband, Guy, initially thought the 3ft boa constrictor was fake - until it flickered its tongue!
The couple got such a shock, they slammed down the boot in fright - we don't blame them!
After calling the car's previous owner, they discovered it was his pet who had gone missing two months ago but he didn't want it back.
Thankfully, a reptile charity came to their rescue and collected the unharmed boa.
We're bet she's glad he's not squeezing in for a ride again!
