I test drove a 1997 SC400 yesterday for the first time. The ride was very smooth, but acceleration was much worse than expected. I thought a V8 with 250 horsepower would have had excellent acceleration. To give you an example, I was at a red light and a delivery van was next to me. When the light turned green the delvery van accelerated ahead of the SC400. Is this normal? What kind of acceleration should be expected?
