It cost me £93.88 Trade / Retail Plugs £6 / £11.52 HT leads £25.31 / £29.48 Fuel filter £1 / £1.99 Oil filter £2 / £6.07 Air filter £6.50 / £11.44 Distributor cap £4.34 / £5.86 Rotor arm £2.73 / £3.69 5 litres of semisynthetic oil £ 7 / £22.53 and i even bought myself timing light to tune her up with! £25 / £46.98 + 17.5 % VAT £93.88 / £139.56 This shows the difference between the trade and retail price i paid for my parts at Partco a well known parts supplier to the motor trade! I know most people use a mechanic but if your handy with a spanner you can use their trade counter and save a lot of cash! They also have a very good returns policy so if you don't need it they will give you a refund! I will give you a trade tip though! When you ask for your parts ask them for price and availability! Its a bit of mechanic lingo and sometimes they knock a bit more off the price for you! Hope this helps!
