I use the halfords orange metal ramps - good price and sturdy, reasonable height and just about low enough angle to work with the Leon low front bumper. If the angle is too steep it will hit the bumper before the wheel climbs the ramp.Ah!
I'm perhaps veering towards using ramps ( + chocks for the rear), I only recently bought the trolley jack (a Sealey 2.5 ton low profile one), so could actually return it to Halfords, though I guess might be useful if I ever need to take a wheel off. I'm a little nervous about getting the car onto ramps, though, can see it could all go horribly wrong if you mess up the approach or overshoot (though I guess having stops at the end make that less likely). I don't have a workshop (or the ability) to fabricate ramps myself, so would need to buy some off the shelf ones - maybe something like these Rhino Ramps. though the top platform looks a bit short?: https://dieselpartsdirect.co.uk/11909mie.html
When driving up them on my own I use the reflection in my neighbors car door to see how far up I am. If you don't have that you could position a mirror to show you where your wheel is.
