When to get a car?

In the end I got a 2015 Vw Up! 1.0 60 BHP version.
Cheap to tax, insure, run, repair and good on mpg.
Not the fastest but keeps up with the crawl on the morning commute,
Just out of the manufacturers warranty though so I might have to sort something out.
Also done 19k miles, so still got plenty of life in it and claims to do 65mpg.
