I was looking into Toyota's Hilux (2.4L Diesel) a while back and decided to look into insurance, let's just say it wasn't pretty... 20 y/o, driving for 2 years (3 years in August), clean licence, no claims. Off the top of my head, I seem to remember it being something f*cking crazy like 8 or 9 grand.
At 17, with zero history? You could probably put down a 50% deposit on a brand new, top spec ranger at the very least, if you could even get insured at all... I literally just did a check on a 07 double cab ranger, for me, I'd be looking at almost 10.5 grand (and most major insurers wouldn't even touch me)... So in other words, it ain't happening.
