Those things are SCAREY fast! I work for Nissan and hear all the stories from tech instructors and field reps. on those cars. Word is they are bringing a "Skyline" state side based on the Infiniti G-35....
And as for Valiant Effort, buy the Sentra. My wife has a `94 that we beat the wheels off of and it never skips a beat. Base model 1.6-auto 4dr. cruncher. 105,000miles and it runs great. Ugly as all hell... but runs great.
