It was quite funny - the owners "munshi" was there when the offending cell was removed from the car, He was insisting that someone put in some chemical in the tank with bad intentions..
To which firstly I had to laugh and nearly spit out my gulp of tea, and then I showed him that the fuel cell was factory loaded with the gel packs in place. Mr Genius right hand man of whoever owned that car was such misinformed that he had the tank cut up, rodded and what not to remove the said little gel packs, which were perfectly fine in the first place.
the new cell was MUCHO DINERO to say at least. (think mucho dinero mafia style) to imagine the invoice.
