So may ways to look at it, think as said above its a personal thing and depends on your attitude to money etc there is no best way in general just what works for you in your situation.
For me i started leasing as i am really fussy with cars and finding the right car second hand for me has always been a task, then having a baby at the time driving around the country looking at cars became less appealing than before having the little one, i enjoyed the chase if you like BC (before child).
Then simple man maths for me looking at a loan for a car, the car i could afford at the time would have been a 3 year old octavia vrs so probably no warranty and the previous generation, when I looked at lease I could have the newer shape, brand new, delivered to my door and for less money a month and fully under warranty...and as I'm really fussy with cars the worst thing happened I got hit in it by an HGV, damage to rear passenger door, wing, wheel etc - went through insurance to repair it, nightmare had it re done 3 times and if it was my own car i would have sold it as in the end i wasnt really happy with work done, but on that last day I handed it back and walked away - so for me its working, is it cheap? I would say no personally, BUT it works for me for now.
