He said people need to consider 'not only the day to day running costs, but also the total cost of ownership - including what the value of their car is when it comes time to change it'.
His comments followed a survey which found Toyota cars retain their value longer than any other brands.
The survey, by vehicle records company Cartell.ie, analysed the residual values of new cars in the Irish market originally purchased in 2010, with up to 50,000km on the clock.
Of the nine categories examined (including both petrol and diesel models in each class size) Toyota ranked first in seven out of the nine categories.
The Aygo came first in the A segment, in petrol; Yaris ranked first in the B segment for both petrol and diesel; Corolla ranked first of all C-segment petrol passenger cars, and Auris ranked first in diesel. Avensis came first in the D segment, petrol while Verso ranked first in the small MPV diesel segment.
The Toyota boss added: "This year, we have launched a huge number of new models into the Irish market including the all-new Corolla, Rav4, Prius+, Verso and Auris Touring Sports, giving the widest and newest line of car models available for any manufacturer in Ireland."
