I recently bought a gauge cluster from ebay as an experiment to see if I could use its odometer LCD in my own failing cluster. I found one reasonably priced on ebay, but for a tiptronic car. When I took a closer look I realized that an LCD swap wasn't possible, and since my car is a manual I cannot use this cluster. My bad luck may become your good one..
Original ebay item:
2000 Boxster Speedometer Speedo Cluster Gauge LKQ | eBay
It's a nice one with silver faces and trim rings, in good condition, from a 2000 car with 122k miles. Recent photo:
I'm asking $65 shipped to the continental US.
