Hi I'm looking at the Opel Mokka, a 2016 (1) 1.4 petrol model. Can you tell me what are the advantages and disadvantages of buying this car? I have been advised to switch to a petrol car because in the next few years there will be tax increases on diesel and a diesel car will lose its resale value? Can you give me your advice about this also? I will be trading in a Kia Venga 2012 diesel with 95,000 kms so if you can give me an estimate of what I might get against the Mokka for the Venga also please. Many thanks.
