You'll be interrupting his tree-hugging hour if you did.
My missus has an old one - not 4wd enough for me.
It's a 2007 GenII, the 1500. It's got almost 145,000 miles with a full Toyota dealer history. It's devoid of character or interest, but despite its age and mileage drives like a new car. Not a single squeak, rattle or knock and still manages easily beyond 60mpg in normal driving - drive it like normal car and yo can get hat to under 40 with ease, but you quickly learn the hybrid technique and big MPGs come easy. It's never had anything except routine servicing and consumables such as brakes, tyres etc.
Toyota massively over engineered them to avoid the huge embarrassment that unreliability would bring and they rack up huge mileages. North of 400,000 miles is not uncommon, and there's a Prius taxi in Canada that's managed over a million and is still working for its living.
There's healthy trade in used spare parts from write offs etc, so when the big hybrid battery goes (typically between 200-250 thousand miles, more in our cooler climate)decent used ones can be had at fair prices. Wifeys is the top spec T-Spirit and its well equipped with JBL sounds, leather, all the toys, but the interior is styled a bit cheesy and looks cheap. However the finish is good and our is only just starting to show wear on the drivers seat
I'm a whisker under 6'4", over 18 stone and have a 52" chest and fit just fine front or rear. The boot isn't so good, with a big footprint but limited in height by the slopey hatch.
Find one that been cared for and you can buy with confidence. The American based PriusChat website is well worth a browse.
