I found a Studebaker Champ all original with a V8 (not sure of engine size), cannot remember whether it was an auto or stick, has no sliding window but is basically faded paint and faded interior. No mods, no dents and no missing parts. It's more than likely a '63 or '64. What should I be making an offer for? As the owner said he could have sold it a number of years ago for $3500.00 to someone who asked about it. Thanks
