my opinion :
Sell the car on ebay, that seems pretty strait forward fix
then sell spares seperate unless they are to repair said problems then that might help the sale
Filled her to the brim of optimax and thought I would give it a quick jet wash while I was there to get rid of the crap
After its drive out it was filthy again
yeah its not a simple reprogram fob thing, remember vauxhalls used to be put ignition on and press the lock button twice and it will do it
mine is taking ages to arm / disarm !
