Ordered a Challenger 200. It took forever to even get an update on delivery date. It took nearly 3 weeks from ordering. They sold it to us and did not even have in stock. After running it around for about 10 miles, the muffler fell off the tailpipe. We only ran it in our 3 acre yard. Nothing rough. I called twice, NO ANSWER, left 2 messages, and NO response. Sent an email, NO response. Sent another email, waiting. It has been over 2 weeks since it fell apart and still waiting on response. They are almost impossible to reach.
