Sorry guys but Budfish is quite right, if you have no recipet then SMD will not give you any warranty at present, the reciept is your proof of original purchase if you read the warranty conditions, once the unit changes hands (ie becomes 2nd hand as in this case) the warranty is over, it is only ever for the original purchaser for a time of up to 25 years.
It is designed to give you peace of mind when you buy it from new, that for as long as "you" own it, for a time scale of 25 years (they had to stop using the term LIFE for legal reasons) it is covered under warranty when accompanied by the purchase reciept for all regular warranty issues.
So many people keep hold of the warranty card which is not how it works, your card (for any and whatever reason) should be filled out as soon as you get it and returned to SMD (or your local dealer) to activate the warranty, not held on to for a rainy day or for added re-sale value use (of which it is no good now anyhow)
Sadly it is poeple who have "twisted" the warranty procedure with LRP that have caused them to clamp down on how it works, the racers only have themselves to blame for this, hell I even saw someone a short while ago on here asking to buy just "a warranty card"...... I wonder why?
