From Lexus to Mercedes to Infiniti

Just sold my 2007 Lexus LS460L and made a mistake in buying a 2008 Mercedes E350. Disappointed with the Mercedes, I went shopping and discovered the 2011 Infiniti M56. Great car all around. Fast, powerful, refined, comfortable and lots of bells and whistles.

Looked an the usual suspects - E550, 550, A6 V8. All nice cars, but none of them had the balance of exterior design, interior style, performance and value. The 2011 MB has no style, BMW is way overrated and need to learn how to do an interior and the Audi needs to be updated. Just look up the performance numbers - the Infiniti has a great ride and is luxurious.

The only thing better than my M45, was the M45X I purchased, then along came the M56X - I got one of the first in the region. Nissan really listened when they built this. Everything has improved, and the additional horsepower puts it into a different league. I love the ride - feels more substantial, and corners like it's on rails with breathtaking acceleration. My wife says it reminds her of our BMW 750 - but more fun, with a sexier interior and exterior. Electronics, back up cam, sound system, etc. all exceptional. They even added a heated steering wheel and retractable outside mirrors. The dial-a-transmission is very clever. Bravo!

Better and worse than an M45

Infiniti has gone to great lengths refining many aspects of the M for 2011 but there are still many things that need improvement. While I enjoy my M56 a lot, there are features that worked better on my '08 M45 (such as XM NavTraffic, which is a disaster on the M56 and every other 2010+ Infiniti model). And there are features that are completely backwards, like the armrest button you press OUT to fold the side mirrors IN, and the song selection button you press UP to switch to the next song DOWN on the list. Doors lock automatically at 15mph and you can't do anything about it. And there is so little ability to customize the warning/intervention systems that one is inclined to leave them off!

Transmission needs work

I'm happy with just about everything on and in the car except the transmission is jerky and undecided as to what gear it should be in at slow speeds. Between 20 - 40 mph, the gears shift up and down over 1K rpm because the computer can't figure out what gear to be in. The car actually jerks back and forth. Infiniti knows about this and is working on it.

Prior to buying the M56X, I had a 2006 M45 Sport. I wanted to stay in the Infiniti family. Most because of the reliability of their vehicles and my experience owning an impressive car. I wanted to stay with an 8 cyl car. Not many people are aware of this vehicle since it debut in 2011. However, with minimum exterior aftermarket additions I LOVE my car even more. Wish I could upload a picture. I have had a lot of people ask what year in my car? They find it hard to believe its an 2011. However, since the Q series have came on the scene people are more gear towards the new looks of the car. I love the way my car drives and feel on the road. Its a bigger car but handles fairly well for its size.

This is my 3rd M and is the the best of the lot in all aspects except one. The transmission is a disaster. It has too many gears and is constantly searching for the correct one. Very annoying. It's a magnificent beast on the highway on a long trip. Not meant to be driven around town.

Having previously owned a G-35X, the M-56X is a beast. It doesn't have the handling characteristics of the G-35, which were fantastic, but the M is a bigger car. The 420 ponies under the hood are just awesome. Broke my heart to get rid of it, but we needed an SUV, so now there is an Outback in the garage. I miss the M already!

Had an E550 that i liked a lot-but it was not very sporty. The interior is much nicer than the e550. the performance is about the same. i love the change but have nothing bad to say about the E550. Also like the larger feel of the infinity.I think the E550 is more expensive when you consider option for option.

Shifting my gear from Beemer to infiniti

I have been driving BMW 550i since 2006 (first release of 550i). I cant deny I had a lot of fun and appreciation toward my Beemer. But I did not notice any subtaintial improvement from the model 2006 to 2008, even the HP remained the same between 2006-2008, this year they did man up to 400 HP...but the price also jump to almost 1.5 times. So I took a look at Audi, Lexus, Acura and eventually ended showing up in infiniti showroom. I was not really thrilled about exterior but the performance of the car is outstanding. The comfort seating, smooth driving and the 420 hp did blow me away. The navigation system, rear view camera, and the gear mode changing are excellent...

We have had this car for 3 years and have taken it in for MULTIPLE MULTIPLE repairs. Once we found out they don't even make the part anymore and had to have the part actually made in Japan and sent to US. Took weeks to get the car repaired. None of the repairs have taken a short period of time. Now a piece broke off and shards of metal went in the engine and they say we need a new engine. After so many times of having to fix this car, the Infinity rep was asked to pay for the new engine and they said no. Why make a part that if it breaks would shatter and go into the engine and cause you to have to have a new engine???? They said they would put the car back together (with the shards in the engine) and if it broke down again they would give us an employee discount on a new vehicle. If it breaks down because of the shards in the engine the engine could just stop, would you want that to happen if you or your child were driving the car? A 2011 model and they discontinued making certain parts for it? They put in parts that if they break cause engine damage!!! Think before you buy.

I have had the car a week, its great fun and cool to drive however if mileage is a concern the car is not for you, it is very powerful with the 400 HP V8.

Have owned many luxury and sports luxury cars. This one is my first Infiniti and the most fun to drive. Excellent power although acceleration is not a smooth as competitors. Excellent ownership experience so far despite some hick-ups.
