buy 2nd hand la - I bought a very good 2010 NT1 from one really good ching for HK$1700 with excellent engine and pipe.
Of course there will always be the people who sell a problem chasis + faulty engine. you just need to be careful. I was very lucky when i bought my NT1, the ching was very good - the car was in super condition (basically, the chasis + engine + pipe: all if new will be 7-8k) and he sold to me for 1.7k. I have control already and only bought 2 servos for 1k, starter box for 250 + some accessories for 500 and start and never looked back. (so whole package less than 4k - and remember 2 new servos war!)
The car was perfectly tuned and the engine was properly run in. therefore my experience was 10 thumbs up!
Now i am planning to buy a world champion edition just for display - and continue to run the 2nd hand car - NT1 : the best !!
