...also speaking of
MBworld, there is
BENZworld and
SLK32 forums...
HDDP over at the other forums they had one member who had downpipes made for his custom headers... but to keep costs down he made a deal with the shop (germany) to retain the plans (pattern) of the pipes so that other members can purchase the down pipes... in the end the downpipes were free as he became sponsored by the shop... maybe you can pitch this idea to them as well???
i am sure
you are setting a trend here for the XF community so they may take the offer. ...just an idea.
ATRIUS... did you say guns???
