Neat site; just found another 66 Electra convertible on there, cheap too! It had the first photo I've ever seen of the cruise control set up I'm looking for and it's location. If I had a truck and trailer I'd go get it; - wait a minute, I need room...oh well nice to dream!
I have found and bought two GS 400's, 67 sportwagon and 65 Riviera GS on this site and try to stay off of it so I don't get tempted again!
I looked a lot on that site, but no modded 59' Invicta or Electra ever I'm sure your guy's keep all the good cars in the U S and A ...
