Not a cent, sorry we don't have copper pennies any more. I'm just a very satisfied customer. Parts ordered include, air filters, fuel filters, oil filters, a used 300td1, sourced from Eng, new clutch, throw-out bearing, drive shaft etc. Had a problem with the oil pan on the used motor, as it was rusted through. He replaced it and shipped it . No charge. The above list does not include many other things, but is indicative of how much I trust him for my business.
