What has been the fastest you have ever driven in a car. What we all want to know 1: What car was it in. 2: How much horsepower does it have (google it if you don't know). 3: Was the road flat/uphill/downhill? 4: How fast did you go? Me, 1: 1996 Honda Accord LX 2: 130 hp 3: It was downhill. 4: 110 MPH (was still accelerating but I had to brake for a corner because I don't want to die yet.) Take a picture of your car if you want.
