Hey Squidioius - Welcome to the group! Typically when hunting for Sterlings, you're better off casting a wider search area and factoring in the price of shipping. There was a guy in Oregon with a bunch for sale. I found a 10-year-old ad of his, but I thought I'd seen something more recently that he still had some for sale.

Also, there are a few FB groups out there, but this forum will be the best place for solid info. There are a half dozen people on here that know these cars better than anyone else on the planet. The FB groups are good for seeing the occasional interesting photo, but this is the place for real help. Also, the folks over at euro-nova.co.uk are pretty knowledgeable, and always happy to help a stateside Sterling owner.
