VRS, Prius, Fabia

Hi peeps

Question

at the moment i have a VRS 2014 TDi octiva

but looking to trading it in for my a fabia 2017 wagon TSI 81kw or a 2014 S Prius

the fabia only got 30,000kms and the Prius as 82,000kms

my vrs has 69,000kms but here in new zealand we have to buy RUC ( road users changes)

which are 88 dollars for a 1000kms, and deiseal is about $1.35 where petrol is $2 litre

so, running my VRS is getting quite expense, i do around 2000kms a month with my commute

so was thinking about getting a fabia or prius

what would you peeps do keep the vrs or get a fabia or Prius?

thanks
