As you wish to avoid jacks and axle stands, I guess you were thinking of the metal ramps that go much higher than those shown above by Peter. Personally, I think those high ones are very risky. I had some long ago and found that they would sometimes slip forwards as you approached. Also, it’s not easy to know when you have gone up far enough before toppling off the ends!
Best solution for you is to fit a remote greasing kit, then you can grease from under the bonnet. Available from Cain at Wolf Performance for around £80 to do tops and bottoms. Note, to actually fit the kit you will still need to get the front of the car up off the ground.
