The Limerick man picked up the keys to his new SEAT Leon ST at Pierse Motors on the Limerick Road in Tipperary Town.
Quinlan's appointment as a brand ambassador comes as SEAT Ireland prepares to embark upon its second year as the official car partner to Munster Rugby.
The deal has also seen SEAT become title sponsor of the Munster Schools' Senior and Junior Cups, as well as SEAT supporting Munster Rugby's pre-season matches in the newly entitled 'SEAT Series'.
Quinlan said: "Before my rugby career took off I actually worked at Pierse Motors, so I am delighted to revisit my relationship with them and begin a relationship with SEAT.
"I am really impressed with the new SEAT Leon ST as it's a stylish looking car, great to drive and functional too."
Gary Pierse of Pierse Motors said: "We are very proud to have Alan as a brand ambassador. We are huge fans of Munster rugby and enjoyed his performances in the red shirt.
"The fact that he is a local man who once worked with us is great; we look forward to working with him throughout the year.
"We hope he enjoys driving the new SEAT Leon ST, which is a very important car for us."
