hi saggar, i am still about, but i rarely post now, if i do it is in lone parents, about food or about dogs 
scaredoflove, i wish i had a like button for your post.
my children are 19, 14, 12 and 10, it is my youngest who is in receipt of dla, and my oldest will be off to uni in september if she gets the grades, so like you they are all growing up, which means next time the car is up for renewal, we may well be able to find a suitable 5 seater car with the right specs
like you though, it wont be long before ds2 will be old enough to drive for himself (you can drive at 16 if in receipt of dla/motability i believe), though he will need hand controls and either drive from his wheelchair, or have a stowing adaptation included for it
like you, when that time comes i will have spent thousands and be left with nothing, but the knowledge that it was worth it for ds2's sake, as without motability he would have been severely restricted in his day to day life
my village has one bus an hour on weekdays, the last one at 6pm, less on saturdays, none on sundays, and the buses used on the route are not disabled friendly, to use one that is, would meaning driving to the park and ride just outside the closest major town, and getting a bus from there
i only passed my driving test in summer 06, once i had separated from my h, so had to learn to drive asap or else we were pretty much housebound, as it was a nightmare trying to use the bus the couple of times i tried it, and also v expensive, iirc return tickets to the local town just 3 miles away for 5 of us was well over £20!
those buses that were not adapted for disabled users were incredibly hard to get on and off, and more often than not the driver would be on the move immediately, giving no time for me to get ds safely settled. i am sure it was nothing more than the fact that allowing more time for us genuinely didnt cross their mind as it wasnt something they were used to dealing with (mind you even the buses with disabled access arent so great once on board for child sized wheelchairs, because they have a narrower wheelbase, and therefore not so stable when going round corners, for example, i used to brace his wheelchair with my arms and legs to stop him tipping over)
taxi services locally are v different from those in a big town or city, they are all mini cabs that you have to book in advance, and iirc in the almost 9 yrs i have lived here i have seen only one private hire car wheelchair accessible. so the only other option taxi wise would be to book a non adapted one and try to find one that would fit his wheelchair in the boot, but that would also then mean that i would have to take a car seat for him, as he does not have enough muscle tone to keep himself upright.
this is why i had to learn to drive asap, but was unable to do so before as i have been epileptic since i was 6 m old, so had to be seizure free for a year before i could get a provisional licence (been seizure free since nov 04 now though still have to renew my licence every 3 years to prove i havent had one)
and the reason i only have an auto licence to drive is because that was the quickest way to get on the road, as well as my sister and her h v kindly let me have one of their cars which was an auto, which they owned and insured and taxed, but i was a named driver and i paid for servicing and anything that went wrong
i got a motability car in the end because i wanted to be less reliant on them, and to show them i could be more independent , as they have been v good to me in the past, helping in ways they shouldnt have had to, even while i was still with my exh, as he did bugger all to support us and was happy to let them do so. it was uncomfortable for me to be in that situation, so by getting the motability car i felt i was more in charge of our lives
maybe there are some who will say that it was my choice to have the amount of children i did, which is right, but i didnt choose one of them to be disabled, and he deserves the right to have a life as much on a par with his peers as he can, so i really really just cannot grasp why anyone would begrudge someone being able to have that opportunity.
and the only way to enable this is by having a car that includes and is suitable for him and us as a family. surely if we went by the rule of only the person receiving dla being allowed to use the car would once again restrict the lifestyle of that person, as it would be isolating for them rather than inclusion
and of course if that idea was stuck to rigidly it would mean that no disabled children would be out and about enjoying life, growing up ready to contribute to society, making past present and future generations more understanding, tolerant and less "scared" of someone with a disability
isnt that harking back to the old days when disabled people were basically hidden away, stuck at home, not sent to mainstream schools, not spoken about, the elephant in the corner?
why shouldnt disabled people get some extra help to have a life ffs,how can anyone begrudge the extra financial help needed to do that? and why is it so important how much may be independently paid for an advance payment? to me that insinuates a two tiered system, those who are disabled and those who are not, and those who are should not be "allowed" to have a reliable new car (which is v v important in case of breakdowns) that they can be sure will be properly maintained.
if i didnt have a motability car i doubt i could afford a car at all tbh, insurance, servicing, replacing tyres, feeling secure that it wont break down (the idea of being on the hard shoulder of a motorway with ds in his wheelchair is a scary thought)
however if ds2 didnt have cerebral palsy leaving him unable to walk or stand, then having no car would be a pita, but manageable.
another long post sorry, but it infuriates me when i hear some of the stuff people come out with wrt how well disabled people do out of the government and how unfair it is
i wouldnt wish anyone to end up permanently disabled but it would definitely do some good if people could live that life for a bit and then see if they feel the same afterwards
