As a 450 owner (who is at the income level needed to afford a G&K converted 450 Smart) took GREAT offense to the "off the cuff comment to the effect that it must of been a 450 owner who did the damage" I can assure you sir only 10% of our parts are compatible, and of those 10 % A SPEEDO IS not ONE OF THEM.
So may I suggest, prior to you blaming a group of auto owners who may have paid up to 2X the current price for current cars, yo look for a more likely cause of your damage, what ever that may be.
