Of the 350 people surveyed, two thirds of respondents had searched for cars to buy online and of these, 59 per cent failed to find vehicles matching their criteria.
A further 24 per cent said results merely directed them to dealers' websites rather than to the specific vehicles they searched for.
Classified auto search sites were a popular choice among buyers, with 55 per cent of respondents using these sites to assist their search.
Remote purchase was not a popular option, however, as 46 per cent of respondents said they would want to meet the person selling the car before making a purchase.
