They have mailed thousands of toy building bricks to homes nationwide with a message asking the public to come along to their nearest showroom, add the toy brick to the SEAT rocket and in return they'll make a donation to the Children's Medical and Research Foundation at Our Lady's Children's Hospital, Crumlin.
Every brick counts and once all the space rockets are complete the SEAT dealers of Ireland will donate €10,000 to the 'Fix Crumlin' campaign.
Don't worry if you didn't receive your toy brick in the post: just head to your nearest SEAT dealer where they'll give you a brick to help complete the rocket and contribute to this great cause.
If you test drive any new SEAT before the end of May, you could also be driving a fantastic new SEAT Leon this summer as you'll be entered into a draw to win one!
Speaking about this fun fundraiser, Joe Quinsey, CEO of the Children's Medical & Research Foundation at Our Lady's Children's Hospital, Crumlin said: "It's great to have support from a nationwide network like the SEAT dealers throughout Ireland.
"Children from all over Ireland use the facilities at Crumlin and we feel they deserve the best we can give them.
"This money will be put to such good use and we'd urge everyone who can to get involved."
Cian O'Brien, Director SEAT Ireland, said: "We hope our customers have received their toy building block and will go down to their local dealer and help them get their rocket launched for Crumlin."
O'Brien added: "The new Leon has been really well received since it arrived in the showroom.
"The ad campaign reminds us how much fun children have, too, when a new car arrives home."
The all-new Leon starts from €18,995 for the 1.2 TSI Reference; €20,995 for the 1.6 TDI Reference 90bhp and €21,675 for the 1.6 TDI 105bhp.
The Style model starts from €21,395, with the FR specification starting from €26,825.
