Fashion-mad Molly from Portsmouth is very embarrassed about her family car. Nicknamed 'Old Banger' for obvious reasons, it's approaching its twentieth birthday and is covered in scratches. Molly's dad has agreed to let her loose on the car, and she thinks with the help of Ali-A and his supercharging team that she can make it stylish enough for any catwalk.

After Molly scrutinises Ali-A's fashion sense, the pair chat through possible new designs for Old Banger. The rest of the family can't see the designs they are talking about, so Dad is worried about his car returning in bright pink and covered in lipstick!

Ali-A hooks up Molly with Sideways Sid, a motoring guru with an eye for design. Sid takes Molly to a university catwalk show in Southampton to try and find an on-trend look for the Old Banger. She has the honour of opening the show and meets Alicja Teper, a designer whose work has appeared in Vogue. Molly's time with Alicja leaves her feeling inspired and ready to make her family car stand out.

She then pays a visit to mechanic Rebecca, who gets to work with Molly fixing Old Banger in the Superchargers workshop. The pair give the gear box a good seeing to, Molly's hands have never been this dirty! Once they are finished, Old Banger is ready for its fashionable makeover.

Sideways Sid returns to help give the car the extra sparkle it's been in desperate need of. But when it comes to the big reveal, will mum and dad be as into Molly's fashionable design as she is? Show less
