Apart from the cost of used cars at the moment makes it near impossible for me to buy a newer model of 1-3 years...
My car does have a good safety rating, but because of its age, mechanically is not very safe at the moment. im not actually looking at in particular SUVs, the Nissan qashqai was just a car that I liked the looked of, fitted our needs and was in the price range with some luxuries included in the model.
Im looking for any slightly bigger car, preferably petrol that can accommodate our needs but due to the chip shortage at the moment, supermini hatchbacks are going for around £4000 and that's from about 2010 onwards! (in my area anyway)
I am aware of the cost of fuel and that was why I posted in the cost of living, to find out if it was worth it. I was already erring on the side of caution with diesel due to what I already knew about it.
In general the comments on here are quite rude- I am not trying to be polluting, an anti-social driver, a bad driver covering for my sins or anything of the like, I simply liked a model and wondered how much people with similar models were spending on their cars so not many of the comments here were particularly helpful and more often accusations!
And to conclude, research does suggest SUVs are safer in a crash for the passangers, and diesel is less polluting if the engine is maintained properly and a newer engine, however if it is pumping out black sh*t from the exhaust then yes, that is terrible.
If anyone is following this thread, I have opted not to buy a new car at the moment anyway but to keep a look out on the second hand market and dealerships until one is worth my money and time with the right specs for our needs.
Thanks everyone for the input :)
