Tite Reach can get to things that are really awkward to get to without, it just means you can work on something without having to get right into a tight space. Todays FWD cars are so tightly packed under the bonnet there's bound to be use for one, have yet to use mine on the Z but it's only a matter of time. Used to be a mechanic for a living for 30 odd years, lost a fair bit of skin in that time, these tools won't prevent that happening, just reduce the number of times it'll happen. Hope that makes sense, not trying to sell these tools, just pointing out how wonderful they are.
And as for engine cranes falling over, one place I worked at lost their transport manager when he sold his electric pottery kiln, loaded it onto a van using the tail-lift, and the kiln started sliding back towards him. The di**head only tried to save it.
Kiln landed on top of him, wound up extremely dead. In front of the wife and kids, too. Not strictly relevant, I know, but you can't rely on being lucky all the time.
