Iv got genuine VW leeds stamp here too, only makes a difference in regards to price of car, when the car is new ish, say first 5 years at a MAX, i personally prefere to see a specialist dealer stamp.
On a Bora, cant see FWSH making much, if someone wants to be anal about it maybe 100 more in value... but im with chuff, that said - you cant trust any service history as anyone can have a stamp made up of their choice
