Low mileage turboS coupes, manual should be in the mid 60's in my opinion. I was in the upper 50's two years ago. There are only 186 TurboS coupes in the US and I bet less than half those are manual shifters. Cabs and tiptronics have typically been selling for less than the turboS coupes. Mine had less than 25k miles but the maintenance history was not recent so I had the 30k mile maintenance done by the dealer as soon as I bought it.

The fix from ECU doctor was around $600, but I also had a key fob rebuilt.

Sent you a PM on the 993TT, thanks!
