He leaves mum Beverly, 45, stepdad Nick, 38, brothers Steven, 24, David, 21, and sister Phoebe, seven, and 18-month old nephew Cody.
Beverly and Nick, of Hough Road, Brandon, near Grantham, said they were pleased with the verdict and are waiting to see what sentence they get.
She said: "She has shown no remorse and she has not said sorry.
"I have found the whole thing really traumatic."
Nick said that he hopes that the tragedy will send out a message that drink-driving will not be tolerated and encourage passengers to urge speeding motorists to slow down.
Beverly said of Mark: "We all miss him every second of every day. It's left a huge hole in our lives that will never be filled."
Liverpool Football Club fan Mark, who was born in Lincoln Hospital, attended Cherry Willingham Primary School and Charles Read High at Corby Glen.
He then spent one year at Grantham College studying joinery, before working in the family furniture making business. Before his death he worked for South Kesteven District Council.
One of Mark's life passions was his Peugeot 106 Quicksilver and he met his best friend Jamie Atter, 21, through the car scene.
Nick said: "He loved tinkering with his car and it didn't matter how big the job was – he would always give it a go.
"I remember one time he had the whole engine out and none of us thought it would run again, but he managed it.
"He would always be helping his mates with their cars too. He would have loved a job as a mechanic."
Mark's brother David said they would all remember him for how thoughtful and kind he was, and his sense of humour. "He was more like a best mate to me – we did everything together and he always looked after me," he said. "There wasn't anything he wouldn't do for me."
Mark's little sister Phoebe said: "I loved Mark and Jodie. I loved Jodie because she was lovely and I loved Mark because he was my brother and he was great. Mark really loved our cat, Shamrock, too, and we all miss him".
Both Mark's and Jodie's families are also keen to stress that they bear no ill will to the teenage children of Butres.
