your a #$%#ing idiot. you think that all cars with big engines get worse fuel mileage, while in fact when japanese talk about efficiency it means thermal efficiency. stop arguing? there exists not a single mustang or camaro z28 that exists for road racing. the c5 vette is a good car, but it is expensive to modify. a used nsx costs just as much if not less to modify. in addition the japanese didn't start making automobiles until like the 60's when their quality was really bad. but i guess you didn't kow that did you. there are actually quite a number of extreme horsepower retro japanese cars. i can name off the top of my head many old 180sx's 240z's mazda r100's and rx3's and cosmos that crack quarter miles in the 10's and even the 7's. so shove it. in addition most american cars do have poor handling. remember the mustang, vette, and f-bodies are only three american made cars that could even be considered to be 'good'. did you forget that f-bodies aren't even made anymore? loser. in addition a z28ss costs about 30k plus options making it about 32k. quite a number of laughable v6 mustangs and f-bodies roam the streets. i dont remember seeing too many domestics other than vettes being entered for international motorsports, or SCCA road racing divisions, much less winning anything. care to refute that?
