For anyone who knows cars, Courtenay is a name that has been synonymous with Vauxhall for a good number of years. First in Norfolk, then nationwide and finally internationally. Courtenays started as a Vauxhall dealership in 1984 in North Walsham, under Chris Courtenay and with the influence of his motorsport background it widened its remit to include performance tuning, most notably turbocharging, with results that gained the company national recognition and coverage in countless specialist car magazines and on television programmes.
