Does it have a short-shifter fitted? If so, that might explain it. The ones off ebay are often for lhd cars so they tilt to the left. Easily fixed apparently but I had it done by my local Porsche specialist so I can't give you exact details I'm afraid.
I brought a 996 turbo and the owner had installed the Ebay quick shifter so it tilted to the left, I just popped it out, spun it 180 degrees and all sorted.
