Any information has to be useful. This means it has to be memorable so you can hold it in your mind to understand it and take action on your ideas. That's what makes for the best car comparison sites.
The problem with cars is there's too much to remember. According to psychologists the power of the short-term memory is 7 + or - 2. In other words whatever we perceive, are aware of, or attracts attention, we can only recall 7+ or - 2 aspects of it.
If I gave you 9 numbers - 8,3,2,9,6,1,5,4,7 - close your eyes, write them down and see how you do. Did you get all nine, an average 7 or just 5.
There's more to a car:
- Performance, engine options - 0-60 mph, maximum speed, handling, road holding.
- Versatility - size, space, configurations.
- Comfort - seating, ergonomics, ride, stability.
- Durability - it's not an issue, forget it.
- Reliability - it's not an issue, forget it.
- Appearance, trim options - just saying you're not interested when you are can set the mind in a spin.
- Prestige - again, an aspect denied by buyers. So why aren't we all running Kias.
- Economy - urban cycle mpg, extra-urban cycle mpg, combined mpg, plus CO2 emissions.
- Safety - education, perception, prevention, protection.
You've 9 features to consider. 2 you can forget. But the remaining 7 involve 3 or 4 issues, so there's 20 to 30 things to think about.
That's why you chunk them into the 9 features above - to make it easier. Take the 9 numbers - you don't have to remember all 9, just remember 3 - 832, 961, 547.
You can see the best car comparison sites are those made easy. They stick to the 9 most important features and don't distract with equipment levels which can be dealt with as trim options.
They only compare 2 cars side by side. They don't try to appear to be clever by comparing 3 or 5 cars side by side because the short-term memory can't cope.
The long-term memory is a different thing. It's absolutely enormous. Psychologists often describe the human mind as like an iceberg - a tiny visible/conscious short-term memory with a huge hidden/unconscious long-term memory. The only problem is that like an iceberg, there's no telling which way the mind will drift. I hope you've kept on course with this post.
You could always Google 'car comparisons sites.'
