The Prince of Wales after the unveilling of a plaque during a visit to Morgan car Company at Malvern, Worcestershire.
The Prince of Wales took a spin in a sports car to the delight of factory staff during a visit.
His Royal Highness seemed eager to take the wheel when offered the choice of seats in a red Morgan '+4' during a tour of the production line in Malvern, Worcestershire.
He was also impressed with the Morgan Motor Company's three-wheeler model, saying: "It's a bit like a Wallace and Gromit car."
Later he tried his hand at the manufacturing process, stamping part of a bonnet cover.
Afterwards he asked the factory staff: "Are you sure I haven't ruined it?"
Barry White, who has worked on the production line for 49 years, oversaw The Prince's effort.
He said: "It was in the right place, but to be honest you can't go wrong." Mr White said he was told to make sure The Prince used protective gloves, but said The Prince was happy to get his hands dirty instead.
The Prince met some of the 180 staff and apprentices on the site including coach-builder 19-year-old Sam Mackintosh who said The Prince was "interested" and "impressed" with his work.
He was also given a toy bear from the factory gift shop as a reminder of his visit. As he left, The Prince said Morgan, which makes 1,400 cars a year, "was a great example of British manufacturing".
The Prince of Wales, as Colonel-in-Chief of The Mercian Regiment, presents each of the unit's four battalions with their new silk colours at Sixways Stadium in Worcester.
Earlier in the day, The Prince, in his role as Colonel-in-Chief of The Mercian Regiment, had presented the Army unit with their new colours.
Each of the regiment's four battalions - three regular, one territorial - received the silk flags, at a ceremony at Sixways Stadium, Worcester.
The colours are an important regimental symbol and would traditionally form a rallying point on the battlefield.
Addressing the 500 soldiers parading for the occasion The Prince said: "I am endlessly proud of you all," adding the colours represented "the heritage, fighting spirit and soul of this fine regiment".
He presented new regimental and Queen's colours to each battalion, wearing the black number one ceremonial dress of The Mercians, in front of hundreds of members of the regiment's extended family, including young children and veterans.
It is the first time the unit has held such a presentation since its formation in 2007.
Addressing the parade, His Royal Highness said: "Today symbolises a special and historic moment of the whole Mercian regimental family, something serving soldiers, veterans, families and friends will all equally feel proud to be part of.
"As your Colonel-in-Chief I am also endlessly proud of you all and especially pleased to be able to share this day with you."
He said the regiment's history had shown the qualities of its soldiers' values, "service, selflessness and sacrifice".
The Prince added: "The last few years have seen tremendous courage, professionalism and self-sacrifice from those who have served on a whole succession of operational commitments."
He also praised the families for their "support and resilience", while the regiment has served abroad - most recently in Afghanistan.
"Today, it is right that as a regiment we remember with gratitude and pride those who tragically are no longer with us and we also remember their loved ones whose lives will never be the same again and who are with us on this occasion," he said.
"We salute those who were wounded in action and acknowledge the consequences of operational services and pledge ourselves anew to support those who bear the cost."
The Prince also said he was aware the regiment faced "real challenges" and "sadness" at the planned loss of its 3rd battalion, when its soldiers return from a tour of Afghanistan in 2014.
The battalion is being cut as part of a shake-up of the Army, previously announced by the Ministry of Defence.
He added: "I wish you all every possible success and good fortune for the future."
