With Matthew Wilson in 2004, he finished as second outright co-driver in the British Rally Championship (BRC) in the Ford Focus RS.
The following year he achieved his first win in an international series in the FSTi with Clark, and with Mark Higgins he was placed overall third in the FIA Production World Rally Championship.
He participated in only two WRC events in 2012, then in 2013 competed as co-driver with Sheikh Khalid Al-Qassimi in the Citroen DS3.
In 2019, Martin co-drove Elfyn Evans with M-Sport World Rally Team with which they achieved two third places as their best results.
Two more wins followed in 2021, in addition to five second place finishes, leading to a second consecutive runner-up spot in the co-drivers' championship.
