As it's a fairly low car, I just get the trolley jack in behind the front wheel at an angle and onto the subframe, there's also, what looks like a lifting point(datum point?) under there at the same point.
A big trolley jack won't go under, so if you buy one, check it first.
I've used one of these pumps for a while, you need one if you have a Smart car, as they have no sump plug.
My cars used for low mileage so I'll only drain and flush it once every two years, but will change the oil every year, as long as you warm the engine up and get the tube in right (measure the dip stick), it'll get everything out. It also saves getting dirty oil everywhere, routing through the old oil looking for the sump plug/washer, it's easy to pour out, so you're not sloshing it around trying to get it out of a washing up bowl and into an old can
