Hi everyone, new poster here, Ive been doing some research on the new euro 7 emission requirements and it appears that the EU published back in April that the new standards will be implemented in 30 months time for "new types of cars" and in 42 months time for "new cars". I have attached the link below. My question is what will this mean for all of our existing low emission zones like ULEZ? I was thinking of buying a used diesel as I do well over 20k miles annually but am concerned that as soon as euro 7 comes out ill have to pay to take it into cities like London and Birmingham. I usually keep my cars for a long time when I upgrade so am not too keen to have to change again in a few years time. I guess my question really boils down to how likely do you all think it is for ULEZ to upgraded to euro 7 and is it wise for me to buy a used diesel at this time? Your advice is greatly appreciated
