I purchased this car with about 12,000 on it, as a former program car. The car right of the bat sold itself as far as performance and comfort went. I fell in love with the rumble of the exhaust..And punch the pedal and you can feel the pull. As for torque steer, we are talking about an big torgue high hp V-8 in a car...Not some little handa with 200 hp and no real torque, so of course you will have this at times. Just hold on and make sure you are aimed in a direction other than whats desired! Torque steer can also be found in any Cadillac fwd with the northstar!

I bought this car for my wife with 30000 miles on it. It has been in the shop several times. Issues with not starting, rack and pinion leak, and trans slipping with 34000 miles. I also found out it was a Hertz rental. So it definitely has been beat on. mileage is not good, city is 14.5 no highway trips yet but definitely a thirsty engine.

For one love the V8 power and leather seats. I purchased car may of 2017. It was getting 22 mpgs on highway driven so me wanting performance and mpgs I looked for cold air kit I could not find one so I to air box out and looked the dinky hole it's suppose to draw air threw I drilled a bigger hole next to it next road trip 26 mpg 70 mph. Then I found diablosport that keeps your ride in V8 mode longer and plugged that in but I jumped to 34.77 mpg doing that. Then u put headers and cat back system. And getting 42 mpg. I love the car now it's awesome. But only gets like 12 in town but just baught v8 mode chip
