i have to disagree on that.
the yaris hybrid is OTD ( so with dealer discounts )only 2500 euro more then the space star and then i compare the high end models of both.
and the yaris is bigger and hybrid and more comfortable
but it got higher cost to replace the bigger wheels or more oil and so more cost on the long run.
also higher road tax to pay
and if you drive for lets say 15 years then you need to add the battery replacement to that cost
not to forget if anything needs to be fixed it will cost more because you have more expensif parts ( hyrbid and bigger car )
but the differents is indeed not that big.. ( well over here )
still prever the space start above the yaris hyrbid because off above but i expected a bigger price diff.
