Hi, I have bought a mazda rx8, purely because i wanted something a bit 'sporty' looking but needed 4 seats! #kids with friends etc#, I have been told although it is a 1.3 engine it is classed as a 2.6 because it has the power of a 2.6, so why if it is only a 1.3 does it use the petrol of a 2.6 ad is under the tax bracket of a 2.6?? - Is there anything similar that could meet my requirements but not cost me so much in fuel and tax and under the 3k price bracket???
