Wrong comparison
IQ is not comparable to the Auris. If you want to compare to the Auris with another Toyota group far compare with the Sirion Gen1 Mk3 (2002-2005).
The First generation Sirion seats 4 and has a boot on par with the the Auris while taking a quarter less space in a parking lot. It also can hit sub-8s on 0-60 in R2 trim for the Clarksonites amidst us (Clarkson still hates it). There are 2 4x4 versions for the ones that need country driving. Even if you drive it like a twit you still hit 50mpg with ease so it actually compares well with the hybrid Auris despite being 7 years older. It also used to cost 9K new.
One problem though - you cannot find them. Whoever got them is not selling and there is a reason for that. It is a manic marmite vehicle. You either hate it or you love it. So by now all have settled with the ones that love them. I got 2 - a chipped and gas converted 2WD for everyday use and a "native" 4WD which will come very handy next few weeks once we get the taste of "global warming" and climate change from those CO2 emissions. It will be fun driving around Priuses stuck on ice and snow (put normal tires on Prius instead of the nearly illegal factory low rolling resistance ones and see its real mileage, it is nothing to shout about).
