I wonder if these are made of Unobtanium? I haven't seen any on the market.

Hi Mark, an' EVery body; I HOPE they arent obtanium? BYT I've this EV =

thing , what? 40 YEARS! The "Wonderful all concouring battery is STILL out =

there? Remember Bob Aronson's "Tri-Polar offerings back in the 70's? They =

weren't a bad baddery. but he NEHVER enough of them. Remember my post BOUT =

BUING THE AMC gREMLEIN CAR? had THAT BEEN DONE THERE WOULD BE e GREMLEN =

RALLIES NOWADAZE?But Production? OTHER than the Citi-car daze, never =

happened, sigh.However I felt that the Toipcar COULDA made it, especially i=
n =

FLA CA , MM, AZ? places that don't have weather? Well they SO. just ot hot =

for human habitation!But thats why Hartops were invented?You serf boards =

would fit fine in the car for the surf being in Phoexix<G>?I SAW that =

billboard on I-10 outsides of Peonix;" Prime seas sides, buy now" A =

beaitiful serfside painting pix was there!I sez;" He MOST know SOMETHING =

that I wasn't aware?"Wish I snapaed a pix!

Sea Ya;

Bob
