The 2015 Airstream Interstate is currently available from 1 dealer on Searchshop with 3 active listings. Median price is $87,995. At 11 years old, 2015 examples are firmly in the used market — service history matters far more than original sticker price.
Asking prices are tightly clustered, suggesting a stable resale market — there is little room to negotiate based on comparables alone.
Most listings sit in Texas, with a cluster around Katy.
For a 11-year-old Interstate, prioritize a pre-purchase inspection by an independent mechanic who knows the model. Ask specifically about common 2015 model-year issues, verify the title is clean, and assume any "we just replaced…" claim needs paperwork to back it up.
