Overall 2010 Infiniti G37 Cons

Fuel Economy: The G37's powerful engine comes at the cost of fuel efficiency, which might be lower than some rivals in its class.

Limited Rear Legroom: The rear seats might feel cramped for taller passengers, especially when compared to other luxury cars in the same segment.

Outdated Infotainment: While it had decent tech for its time, the infotainment system might feel outdated compared to more modern systems in newer cars.

Ride Comfort: The sporty suspension might make the ride feel a bit firm or rough, which might not suit everyone's preferences, especially on rough roads.

Lastly, Two Very Important Issues:

1. Things To Do When Considering An "Older" G37:

Get an Instant Used Car Appraisal at Edmunds.com

Locate Lower Mileage Vehicles: They are certainly out there to be found with careful and patient shopping. Be willing to drive a distance if you have to.

Vehicle History and Maintenance: Ask for the vehicle history report (CarFax or AutoCheck) as well as documented maintenance and repair records. If not provided by the dealer or private seller, it's best to move on.

Pre-Purchase Inspection: Have the vehicle independently inspected before making a final decision. This usually will cost in the $150-$200 range but is well worth it given the potentially thousands in savings over the long term.

2. Learn How To Negotiate In The Most Effective Way:

Get Dealers To Compete For your Business: When you are searching vehicles to possibly purchase, the following is the absolute best way to get the lowest price, and it is extremely easy and stress-free.

You need to go to a national car listing website and select several vehicles you may be interested in. Then click on the "Check Availability" box or the "Contact Dealer" box, or whatever the site you are using uses, for each vehicle in order to set up the competition.

Then, in response to their email or call, say something like:

"I've contacted several dealers about cars I am interested in and am looking for the best value. I am also a serious buyer planning to make a decision soon. Please send me your best out-the-door price. Thank you.

After receiving the offers, follow up by explaining that based on the price, you're leaning in another direction but still really like their car and would certainly consider another offer. When dealers drop out, you'll know you're at the best price.

I happen to prefer the car site Edmunds.com for this due to their massive dealer participation and ease of use, although other car sites may get the job done as well.

Using the internet to get dealers to compete for your business is extremely important. More details on this and how to intereact with the dealers can be found here at Best Used Car Buying Techniques.

And Related ... Always Know The Value Of Your Trade-In

Whether you are trading or selling on your own, it's just a good idea ... even whether you are in the market or not at the moment. You can then use this important information for a number of purposes ... to negotiate with a dealer, or to know how to price your car in the retail market, or simply to know the value of one of your assets, which is always a good idea.

Getting trade-in values online tend to vary a lot from site to site. But I've found the one at Edmunds Trade-In Quotes is particularly comprehensive and accurate.

It's free and just takes a couple of minutes. I think what helps its accuracy is the inputs will include either your plate# or VIN# followed by many simple, but specific, yes/no questions. It really focuses in on the detail of the specific vehicle.
