I bought a P38 on coils mainly because the car is in such good condition, I intend to convert back to air at some point. I wrote to VOSA regarding whether it would pass an MOT on coils next year. I received a reply about three weeks later stating that they are aware of this type of conversion and provided it is done properly there is no reason why it should not pass an MOT, the handling was not good when I bought it, the shocks were very tired so I replaced them with Koni Heavy Tracks much better now.
