This is the way to go.
A good friend bought a nice e39 touring, got understandably excited, and decided to take care of a bunch of maintenance items. We ordered a water pump, belts, fan clutch, 02 sensors, fuel filter, plugs, coil boots etc and planned to go at it. He says "this shouldn't take more than a couple of hours huh?" I said "well, number one, I've never worked on an e39 and two, you're doing the wrenching, so don't plan on being home for lunch" He's a carpenter, so knows his way around 'tools', but it was funny watching him get the blue shower when he drained the coolantI literally sat there and drank tea while reading the bentley and pointing at tools. He couldn't believe how much time the little things like getting the car in the air and draining fluids can take.
Someone else for a change............
