1 pointIf its not a steep slope, hard to tell of the Pic, if you went on a bit further and then reverse back onto some caravan type leveling ramps to raise the rear end up to level? Something like this: on mine ths issue isn't the holes in your picture its the ones at the front corner (large arrow) and the water pools at the back (small arrow). Mine only leaks if i open the boot that I've noticed after cleaning but it lives in a garage. My drive slopes upto the garage.
1 pointI have done this with a DAB antenna cable. I lifted the car and removed the rear under tray. You can then access the car into the centre console. Takes a bit of time but is ok to do. I used a workshop ramp to lift the car. Hope this helps. Nick
1 pointAt standard height you'll be fine. Both of my previous lowered Elise's coped OK as well, as long as you straddle or angle it. Regardless, you need to take them slowly, which can result in slow progress along heavily bumped roads....and tailgating SUV's 🙄
