I drive about 30000-35000km per year. In two year's time I will sit with either one of the following:
1) 2011 Jetta, 9 years old, +-260000km, value +-R50000
2) 2014 Jetta, 6 years old, +-130000km, value +-R110000
Not sure about the value estimates so it could be R20000 more or less.
What this means is that I will lose R60000 on the 2011 Jetta over the 2 years as I can trade it in for R110000.
I will spend R100000 to 'upgrade' to the 2014 Jetta and it will lose value of about R100000 over the 2 years.
Looking at it that way it definitely confirms what most of you have been saying, keep driving the 2011 Jetta.
