It took Jason and Daniel Knust ten years to save up for their single mum's dream car.

Tis the season of giving – and these two generous boys have gifted their mum the ultimate present this Christmas.

Wollongong brothers Jason and Daniel Knust have selflessly put away money every year for a decade to save up for a dream present for their single mum.

In a sweet video on Facebook the two brothers revealed a ‘gratitude’ gift of a new car to their stunned mum.

They wanted to thank her for everything they had done for them over the years as a single mum – including juggling a number of jobs to provide for them.

“There’s something in there for you”

In the video you can hear one of the brothers telling their mum, “you know for years how you’ve wanted a BMW, a new car?"

The other brother quips, “they’ve got a pushbike coming out”.

The two boys then lead their mum into a garage and point and say, “there’s something in there for you”.

The mum backs away from the boys and says, “no, no, no” repeatedly.

The mum tries to move away from her boys, not believing the gift. Picture: Seven News.

A beautiful new car with a big bow!

They then show her a shiny new car with a big red bow, and she is in complete disbelief.

She looks at her sons and continues to says “no, no, no...”

They hug her and take her closer to the car but she is still stunned! She even tries to wrestle away from the car still not believing it's all hers, and they have done this for her.

What a beautiful gift! We bet this mum treasures the present immensely as a big reminder of her boys' love and gratitude.
