American sports cars are better than European ones

This is absolutely ridiculous. When my opponent posted in the first round asking for definitions, we lost a round in what was effectively a 2 round debate. I initially thought that it was because he was new and did not understand how DDO works. I gave him the benefit of the doubt and told him that we will just use round 3 to post opening arguments with no rebuttals. I also suggested that he use the comments section for further clarifications. If he did not like the fact that "better" was open to interpretation, he should have discussed it in the comments section. After his second round post, I can see that he is not intending to follow any of the guidelines I mentioned (which I have a right to set since I am the instigator). The narrow definition of better is undebatable. I specifically stated that better was open to interpretation so we can argue better in whichever way we like. Instead he asks that the voters disregard any new definition. I ask the voters to disregard his definition as he has shown poor conduct. I will argue my point in this round.The resolution was "American sports cars are better than sports cars manufacted by European, Asian or any other"1) Chevrolet Corvette vs Toyota TundraToyota Tundra is not a sports car. It is a truck. [1] Since it doesn't meet the requirement, my opponent loses this one.2) Dodge Viper vs Bugatti VeyronThe Bugatti Veyron costs more than $1,7million [2]. The Dodge Viper only costs a little more than $90,000. It is much more affordable and a better value for money than the Veyron. It also gives a fuel economy of 13 city/22 hwy mpg [5].It goes from zero to 60 mph in only 3.7 seconds [5]. The Bugatti is not much better while costing a lot more. You could buy about 15-20 Vipers for the price of the Bugatti. 3) Ford Mustang FR500GT vs Jaguar XJ220The XJ220 was a massive failure. The car that the manufacturer's tried to build with a V12 never materialized. Instead they were forced to build a puny imitation containing a V6. They had over 350 people who wanted to buy them but reneged on their contracts because Jaguar did not live up to their expectations. They actually had to sue their customers [8]. The FR500GT was a great value for money. It was also highly aerodynamic and could race on a track for an entire season without an engine rebuild [9].The Jaguar's 0 - 60 mph 4.0 seconds and costs $345 000 [6]. The Ford Mustang's 0 to 60 mph comes in 3.9 seconds and costs $225,000[7].My opponent was just supposed to just pick the cars in the previous round but instead he made his argument. If my opponent posts in this round, I urge the voters to disregard his entire argument since he has unfairly manipulated the debate to get himself an extra round.

He also provides no sources, just claims that he got it from the manufacturer's website. If he posts the sources in the next round, disregard them (see above).
