Misleading and incorrect product info - Quoted for

We have shown interest in a car advertised by Imperial Toyota Kempton Park. The deal was about to be finalized and a holding deposit was paid to the dealership in order to ensure the vehicle is allocate to us. The final step was for us to drive to Kempton Park to view the vehicle, which we did. During discussions prior to this, I confirmed with Louis several times specification of the vehicle in accordance with the adverti*****t to ensure we are buying what we have been informed of. Trendline Polo vs Polo base models as the spesifications differ with specific reference to the Kw output. On arrival to the dealership on Saturday, I noticed when looking at the owner`s manual that this vehicle was indeed not a Polo Trendline but a Polo Vivo base which was far slower than what we expected as we were told this to be the faster model. We were not happy at all having been informed incorrectly about this car and driving all the way from Bloemfontein with a close to final deal on a product different to what was advertised and quoted on by Imperial Toyota.
