Plus many more items as I get them removed, this is just off the top of
my sleepy head. If you are still reading and wish to check back on my
auctions from time to time, you may go to the link below which lists all
of my auctions. I will also have some auto tools and other misc. items
listed, but "miata" will be in the title of all of the miata parts
auctions. I am obviously going to be very busy and may have limited
internet access  until this Thursday, (quit smiling Leon) ;-)
so please bear with me if I am slow in responding to any questions until
then.

I am going to wait at least a week or until I have a large number of
miata items up before posting this again. Anyone in the central
Texas/Austin area that wishes to look at any of the parts before bidding
on them or buying them are most welcome to stop by.

Thanks!
