The campaign, created by (Beta), breaks today (25 March) and features three 10-second ads that run across the ITV, Channel Five, Channel 4 and Sky Media channels for five weeks. Media buying is being handled by The 7 Stars.
The spots feature a couch fired from a catapult, a pram bouncing from a trampoline, and a car being lassoed by a speeding plane. They use the strapline "It's local, its quick and it's free".
The ad has been directed by Wayne Holloway and produced by Scott Taylor, with creative directors Phil Cockrell and Graham Storey, and copywriter Stefan Tarr.
Sam Taylor, from Gumtree.com, said: "We are starting to see great traction from the ad campaigns, and with improved regional functionality following last year's relaunch, the national TV campaigns are a good way to communicate the speed and simplicity Gumtree.com offers."
The campaign follows the success of Gumtree.com's first TV ad campaign last year, called "tree", by (Beta).
Gumtree.com recently surpassed its benchmark of 10 million visits per week, and has 13.7 million users.
