My parents bought one when I was born ('85) for keeping baby stuff in when travelling, its still going strong today!
Its been all over Aus in the back of 4wd (wagons) and spent a lot of time in the boat too.
It wasn't working too well on a waterskiing trip about 18months ago, and when they got back the snapped up a new one on special. I switched it on a week later and turned it to max when I ran out of fridge space for beer, figured a poorly working engel was better than nothing - the damn thing froze my beer!! Seems that getting a new one scared it into working again (rather than getting left home)
Mum now has that same lil old engel in the back of her Honda Jazz to bring the shopping home in.
