What the F@#& was chevy thinking?

It's not just Chevy or Cadillac. My wife's daily driver is a '98 Olds Intrigue. I couldn't believe it the first time I went to replace spark plugs and couldn't get a wrench setup on the back 3 plugs of the transverse mounted V6. I finally gave up and took it to a local shop to replace those plugs. The mechanic told me you have to disconnect the motor mounts and rock the engine forward in order to get adequate access to the back plugs.
That's insane!
Used to have a 89 Taurus SHO. Had to remove intake to get to rear plugs on it. Current DD is 95 S-10. Have to remove front tires and disconnect steering shaft to change plugs. Engine had to come out to change oil pan gasket. Exhaust manifolds had to come off to remove upper control arms to replace bushings. Setting timing requires tearing apart the interior to get to the computer to disconnect the timing wire.
