Just a quite go on the calculater will show us:
Diesel @ 50mpg 13ppm 550 miles to tank ?135 tax 10k per year ?1435
120 petrol @ 40mpg 15ppm 440 miles ?190 tax " " " ?1690
180 petrol @ 30mpg 20ppm 330 miles ?260 tax " " " ?2260
We all know you need to drive a petrol like a grandad to get those mpg's but the diesel gives that as an average driving normally
The more miles the more cost difference. I have owned all 3 cars and I will now stick with the diesel. I loved my 180 just can't afford to run one now.
On another note as far as prices for diesels I paid ?2700 for a 55 plate diesel with 20k on it and full 180 kit as standard in March.
