which should i go for guys, I've had 3 starlet turbos in the past but im weighing up my next move - should i buy a glanza or should i buy a version 4/6 subaru impreza sti - they run about 280bhp standard, but cost double the insurance/tax and petrol to run almost... is it worth the outlay or should i get a glanza? looking for honest opinions guys please, the car will be used as a wkend toy/occasional track toy.
