Motability is changing following on from the switch from DLA to PIP beginning April 2013.
I am not the only one who is worried.
I signed a contract in late August/early September 2012 when Motability itself did not know what would be happening, yet they did not caution me about entering into a 5-year contract when things were still 'up in the air'.
Here is a .pdf file (which opens in a new window) laying out the intended process. www.malosaweb.com/FINAL PIP Flyer.pdf I got it in the first few days of October 2012, not from Motability, but from the dealership I am getting my new vehicle from.
