ROFLMAO!
In the basement of course. When my dad gave away his last Puch 500 car (similar to the Fiat 500 for those who are familiar European cars, but with different engine and transmission) in the late 70ies he kept a full set of tyres, and they're still stacked in our basement.
Right now all things are up side down here (we've been practically gutting our hallway) but I'll try to find the basement keys and then I'll have a look at the radio.
I remember I fitted a new cord with molded Euro plug for some reason, most likely the old cord was cut off (my dad found the radio in an attic when helping clear out the house of an old aunt who had passed away).
That house must have been incredible. He says they loaded our Mitsubishi van _full_ of clothes three times (!), and that still wasn't all. A lot of stuff was still in its original packaging, unopened.
