Nothing.
I was hesitant to buy this car because it was between this one and a Prelude. I chose this one because it was cheaper. It was the best decision I have ever made. This car has never given me a problem.
Also, even with 151,000 miles on it, I managed to crank it up to 130 miles per hour, and it purred like a kitten. I have only replaced the alternator on it when it reached 130,000 miles, and I needed to replace the muffler. I have yet to replace the timing belt.
Replace the timing belt before its to late!!!
