Dave, who has worked at Bolton Market for three years, said: “It’s like a big family in here.”
Last week, the couple were told that they would be getting a secondhand scooter using the money raised by the traders who put their hands in their pockets.
Dave said that the "sweet" couple couldn’t believe it and Sylvia started crying when she found out.
On Tuesday, Dave and Nigel surprised the couple with a new scooter worth over £1,000 which Terry had his eye on.
Their daughter Tina, 57, was at the market to receive the gift with her parents who will now be able to get on a train to visit their daughter in Edinburgh and son in Swansea.
She said: “It means everything to them. No one has ever done anything like this for them before.”
In his younger days Terry was a soldier and also worked down the pits, Tina said.
She added: “Even as a child, I just remember them both working. They never had much but always made sure we were okay.”
Aside from Parkinson’s disease, Terry suffers from pneumoconiosis, a lung disease common in coal miners.
When the scooter was presented to him, Terry said: “It’s brilliant. It means I can go around on my own.”
