** Useful information first ** If you plan on buying Mopar Lifetime warranty, google "mopar lifetime warraty". There will be at least 3 legitimate website that will give you a quote online. They will be roughly $1000 cheaper than what these guys offer. Arm yourself with a knowledge before facing the battle.
Also, make sure your agreed terms are in the paperwork. I cannot STRESS this enough. They will try to cheat you if they smell you may be gullible. If you want to know why I came to that conclusion, read on.
My wife bought a jeep wrangler while I was out of town, and since she was not good at negotiating, I dealt with them over the phone. A guy named Andrew in Finance agreed to sell me $0 deductible lifetime warranty for $3500. Upon arriving home, I noticed they did not give her a copy of the warranty contract, and that got me suspicious of a foul play. I went online and retrieved her warranty on Mopar website, and sure enough, it stated her warranty was $100 deductible plan, which costs $1800 less than $0 deductible plan($2965 vs $4795). I went to face them, and they had to cut me a check for $500 when I told them I am cancelling warranty (difference for what they were supposed to charge in the first place, not a penny more). I demanded apology from Andrew for the deception, but the guy kept claiming it was a confusion or miscommunication, never really admit his wrongdoing. The management got irritated and even hostile when I tried to clarify what really happened. They don't seem to treat this fraudulent activity seriously, which suggests this may be a common practice for them.
One last thing, the trade-in they give you will be lower than the competition. They tried to give my wife $10500 for her 2014 Murano. They had to match the price when I told them the other dealer appraised it at $14000, a whopping $3500 difference. Now they are selling it at $16991. The starting price they appraise seems few thousand dollars less, so know your trade-in value at KBB, Edmunds, NADA before the negotiation.
Overall, this dealer was unpleasant, dishonest and highly risky. I recommend driving few more miles to any of 4 other dealers in DFW area.
