Not wanting to burst any bubbles but I recon I could do 900 miles for around £90 in the wife’s Skoda Karoq Diesel.
Are you stating your wife’s Skoda car ache over 60mpg on the UK motorways, at 60mpg = £95.25, at 50mpg = £ 114.30
Unfortunately I have suffered a brain injury and occasionally I get confused and often say the wrong thing.
