If it is a factory turbo diesel, then I drove one just like it in Canada a few years ago. I wish I had one just like it. It was actually quicker than the 3.0 V6 that came standard in the Limited. Much better fuel economy along with typical stellar build quality. I got 12 mpg city in my V6 and I think I remember getting around 20 mpg city in the TD.
I never understood how Toyota got away with giving customers crappy mpg along with lousy performance. If mine had gotten 18-19 city mpg and lousy acceleration, or 12 mpg and great performance, I would have kept the car.
