I also own a 1994 SVX L and I will be taking a road trip from Los Angeles, CA to North Idaho (1100 miles). Your experience serves as wake-up call and makes me realize what a powerful machine I drive. Power-Mode can be fun and exhilirating but, as in Deruvian's case, it can also be detrimental and risky. I will be setting the cruise control at 60 while on Interstate 5 heading North.
