Sexy, Reliable and Paid off...I am in Heaven.

I bought this car in 2012 with 79,000 miles. It has been trouble free with the exception of some starting problems which were fixed when we replaced the starter solenoid. I was initially looking to buy a Lexus, but I found that the Lexus would have cost me an additional $5,000 over what I paid. It is nice having 340 horsepower, which provides oodles of power when needed. For mileage I get 23 mpg highway. I have had this car now for 8 years (now a 17 year old car). I plan to keep it at least another 5 years. In summary, this car is sexy, reliable and paid off!

Most Reliable, SOLID, The Best

Only 1 owner before me, literally a traveling salesman. He used the car to impress so it looked good, but didn’t take care of it. He got into an accident and dumped it for another. I got hold of it and brought it back to life, and it hasn’t let me down. An ordinary mechanic gets frustrated because the engine and underside are covered in plates and protected, but the car runs clean like a dream. The gas is too much these days tho, and I’m trying to keep the car, maybe even put in a smaller engine. They are making cars smaller and smaller and I don’t want a new car. Wish me luck!
