(I believe it's the same wheel-base as a Fiesta, but with a hatchback style boot.)
I put the seats down in the back of the car, and have a 'hatchbag' boot liner fitted (a big plastic cover made to the exact dimensions of my boot which velcro's into place) which stops the muddy wheels from damaging anything.
I then pull out a portable ramp (stored in the car). and drive the chair up to the start of the ramp so it's all lined up. Then I set the 'steering lock' (so I don't accidentally make it turn and drive off the side of the ramp!)
Then unclip the back rest and put it to ones side, detatche the joystick and drive the chair up the ramp and into my car from my remote position.
(Here I am loading the X8 from mostly standing. I prefer loading from my manual wheelchair. Although there is always the option of training someone else up to do it!)
Then slide the ramp, back rest and bag into the car. (you can see the backrest, which is remarkably light, in the bottom right of the picture.)
It only takes a few minutes.
And it means I have my off-road freedom without needing an expensive wheelchair accessible vehicle.
For longer journeys, and ones where I want to go with a car full of friends and luggage I plan to get a trailer.
An ifor 'williams' P5 trailer with fibreglass roof and 4 lashing points internally seems the best option - secure, weatherproof, easy to load, light enough for small cars to tow and it can be towed on most standard UK driving licences as total weight of chair + trailer is under 500kg.
As my X8 has a powered reclining back-rest I had a few moments of panic as the arm rests don't fold low enough to fit under the lid - even with the back rest reclined...so I messaged the guys at Magic - and sure enough, removal of 2 quick-release pins and the seat cusion (velcro) and it folds up even smaller than in the pictures. (I had been told about these when I got the chair, I was just rather distracted by finally getting the chair.)
I can't guarantee that the chair fits inside the trailer yet, the trailer chap at TH white will let me know when they have one in stock for me to 'test'. At which point I will blog it - so you can see for yourselves whether it works.
