Leasing a 2011 Infiniti G37 Sedan, and saving $6000 off of MSRP.
Test drive as many cars as necessary to be sure you have found the right car. I drove 23 cars before settling on the G37X. Dealers won't like this, but you should know you made the right decision when you are spending >$10,000.
Find a dealer that treats you with respect. Birchwood Infiniti is the only place in Manitoba where I could get a new G37X, so I had to be willing to go to another province if things didn't go well. Luckily they did. I found someone who treated me with respect and he came through at a reasonable price.
The report was mostly useful as information. I knew what my expectations should be because I could judge a reasonable amount of profit for the dealer. When it looked like the deal might not happen, I brought it out and it kept the conversation moving. I would definitely recommend getting a report to anyone looking to buy or lease a new car. It is definitely worth the cost.
