You could also buy the Wall Connector, which I believe has a 24’ cord (check though). I ended up in the opposite situation. I actually routinely back up into my garage since I bought my Model X to allow the Falcon wing doors to open up fully, but the the front of garage charger is now at the wrong location.
For a while, I just charged that way (had to throw the charge handle under the car since the charge port was on the opposite side too), but now I just will park front ways in when I want to charge.
Anyways, my point is that backing your car into the garage is actually fine, better even in some ways. The trunk is now closer to your house access door presumably. I put a strip of tape on the ground that I can view in my backup camera which tells me exactly how far to back up. And leaving is far easier and quicker.
