Re: 10/12k mileage per year — petrol/diesel?
Fred, I was working out the exact same figures about 2 weeks ago and funnily enough, I used the new Octavia as an example.
I still have the spreadsheet I used and I put in your mileage and this is what it produced. Also depends on the difference in the litre you pay for diesel or petrol, but I based it on my local garage that charges 3c more per litre for petrol. Calculations also based on the combined fuel consumption quoted in the brochure for the Octavia.
If you buy the 1.6FSI petrol over the 1.9TDi diesel, you will pay an additional €394/yr in fuel costs. The petrol car is €1105 cheaper than the diesel, so it will take you 2.8yrs to break even.
If you buy the 1.6MPI petrol over the 1.9TDi diesel, you will pay an additional €590/yr in fuel costs. The petrol car is €3110 cheaper than the diesel, so it will take you 5.9yrs to break even.
Above calucualtions do not take into consideration the road tax differences between the different cars or servicing costs, which with a bigger diesel engine, could increase the length of time to break even.
I suppose it all depends on how long you plan to hold onto the car.
