Look at your door sticker, "Built by Karmann in Germany..." It's an SLK32/320 as far as engine/powertrain/chassis goes. It's a "Chrysler design, built by Karmann" as far as body.

I should have mentioned in the other thread that MANY items are interchangeable with the SLK 32/320. ('32 for SRTs and 320 for N/As)
