So I read every post so far, laughed a few times. Not too many things mentioned are actually difficult. I'd rather do a starter on a Northstar while staying clean and just bending over the engine then doing one from the bottom on some oil leaking shitbox. Toyota 4.7 starters are waaaaay easier then the 5.7's tucked under the exhaust manifold. The secondary air pump is under the intake too, again, an easy job. Bmw 6 cylinder starters can be done from the bottom in 5 minutes if you have swivel E-torx sockets, they pay great. No transmission is 'sealed', they're all serviceable, but if needing a special tool to fill them keeps the ding dongs out, then I guess mission accomplished. Even the cars that require bumper removal for headlight replacement are actually pretty easy.
