    "Came very fast. I ordered it round a lil before 1 on a tuesday and it was at my house friday morning. It was the right part and the price was way less than if I had bought it from a local auto parts store. Two things to know; you need to be sure everything that caused it to go bad has been fixed if not you will eventually kill the new one so get your check engine light off first. Clean out your egr valve if you didnt need to replace it might as well replace your pcv valve cuz its only $3 and clean out the area where its seated and if an O2 sensor is bad replace it the only two on this car (2000 model year) are right in the area of catalytic. Also if your flex pipe is bad you can just a flex pipe so you may be able to piece it together without having to buy the converter with the pipe to manifold. I ended up replacing or cleaning almost my whole emissions system to get it to pass the state test. With the help of this site and my own ingenuity what would have been over $500 in parts cost less than $140 not bad at all!!" posted by: In Cleveland on January 26, 2014

    "DURABLE is the word for these mats. They undoubtedly will outlive me! I have to wear rubber soled shoes. The mats interfere with my shoes especially getting into the car. I will adjust! The mats don't fit perfectly, but we trimmed them down. It wasn't an easy task, but doable. They are very heavy, but easy to hose down. I would definitely recommend them to a friend. My car is 16 years old; I hope I remember to remove these mats when they haul my car off to the dump!!" posted by: Mrs 504 on September 19, 2009

    Date Published: August 15,2014

    The Struggle of the Infiniti Q45

    Infiniti had high hopes with the Q45. As one of the first two models from the company, it was a luxury vehicle designed to directly compete against European cars in the same class. For almost two decades, the car tried its best to be recognized as a legitimate alternate to the likes of Mercedes and BMW. There were highlights spread few and far between. For the bigger part, its shaky history however tells a story of a car that simply wasn't effective in capturing the hearts of buyers. Whether it's due to poor designing, planning, or marketing, the Infiniti Q45 is one of those cars that definitely could've done better under the right circumstances.

    First generation (1990-1996): Definition of modern luxury

    The Infiniti Q45 debuted in 1990. Modeled after the Nissan President, it was a rear-wheel drive car powered by a hefty 278 horsepower, V8 engine. In some ways, the Q45 it was a mash-up of the good qualities of its competitors. The car also featured looks and amenities worth mentioning. The body seems similar to the sleek looks of a Jaguar. Handling was great and stiff enough similar to that of a Mercedes. With help from an Italian furniture consultant, luxurious ingredients were added to it: leather seats, power steering wheels, mirrors and mirrors, computerized controls, and a keyless entry system to name a few.

    The overall makeup of the car was undoubtedly great. It transported luxury cars into a new phase. The Q45's initial look could certainly send its competitors straight to the drawing board. However, because of obscure advertising, and the low credibility of the up-and-coming Infiniti name, the car wasn't able to attract many buyers.

    Second generation (1997-2001): Infiniti's new approach

    Despite being a great car, the Q45 hasn't been a success in a marketing perspective. What Infiniti did was to change the car itself and hopefully appeal better to buyers. To do this, second-generation Q45s had major upgrades on the looks, style, comfort, and luxury department--somewhat based on the Nissan Cima. 17-inch rims, HID lights, and power-heated mirrors are some of the upgrades outside. Inside, the car was dressed with leather seats, an improved stereo system, navigation system, and wooden trims.

    Rather than achieving a balanced car, the new Q45 leaned towards the side of luxury. Engine and mechanical upgrades were almost forgotten. The powerhouse became smaller and less powerful. Handling was negatively affected with a new suspension system that focused on comfort. To nobody's surprise--except for the heads at Infiniti--the car still failed to attract more buyers to be a success.

    Third generation (2002-2006): Too late to compete

    The last Q45 returned to its roots and achieved a good balance between luxury and power. Features included leather interior, navigation system, sensors, and various electronics. Its 340 horsepower V8, though another step down, was a big leap compared to the engines of its competition. The ride was also smooth, quiet and comfortable. This is another great car that pleased critics.

    Sadly, it was too late for the Q45 to make an impact. Sales continued to plummet because of bad advertising. The inevitable discontinuation of the Infiniti Q45 happened in 2006.
