I'd highly recommend CJ Autos individual scissor ramps. Available in pairs and four are really useful. see link below. I've owned my set of four now for about 3 years and used them on 3 different cars, with any car or small vehicle being suitable (ride on mower was handy too!). It's made life so much easier and safer !
Compared to scissor jacks that you need to locate along each side of the car and usually need pucks or chocks to find suitable lifting points, these drive on ramps lift the car at tyre level. Therefore the lifting height is from ground upwards if that makes sense? Lifting the sills of cars by the same amount obviously doesn't lift the underside so high. Plus I also calculated (and have found in practice) that it is quite rare that you need the wheels off or even in the air, meaning the drive on are more practical.
Heavy-Duty Scissor Hydraulic Car Ramps with 4 different locking heights and super low entry ramp. These will work together or independently.

Each unit can be operated individually so this means you can get all four wheels onto the ramps, lift the car and if you just need one wheel off or both wheels on one side you can place axle stands appropriately and then lower the individual ramp/s so that you can complete your task. If you have four ramps you need to drive up to the front set, slide the rear pair underneath, aligned to the rear wheels and then drive on. I have mine on rubber matting to avoid them sliding.
I've used them for servicing, maintenance, spraying and under-body treatments (as can be seen in pic treating my the underside and sills of my 944).
I rarely lift them as far as the 4th hole safety lock as often that's too high when reaching up from beneath.
They have a good lifting weight so even a small SUV below 1360kg per axle/pair is OK. Each ramp is 34kg so I find sliding them around or using a small trolley is required but technically they are portable to take where ever you want to use them. I've taken them to a friends before to help lift a car for a small welding job.
