I doubt he would say drive the car correctly and you will be fine but I have with literally double the power to the wheels. 4 cars, not one issue. They were lower mile cars not 75k. I think around 13-15 is the right miles to buy one of these cars anyway because look at the amount of miles, owners and drive train beaters that have been behind a 50k TR. I will never put 20k on my 13k 90 model and I bet anyone here any amount of money my differential is perfect when I sell it. I will put my money where my mouth is every time. Not being a smart ass, I just know what I am talking about, been there and done that numerous times, not just once. I by far don't know it all but what I do is what I speak about.
