Just been to GSF Auto Parts to get some parts for when I service my car. They are basically Partco/Unipart but a hell of a lot cheaper - i picked up 4 HT leads, a fuel filter, an oil filter and 5L of oil for just under £40 inc. VAT. Just thought I would let everyone know their website so they can see for themselves
