As the second-generation Q45 enters its third year of production, Infiniti hopes that new exterior and interior appointments will help keep the vehicle flying high in the luxury performance sedan class. To that end, Infiniti continues its quest for enhanced comfort and convenience rather than building on the sporting nature of the original Q45. The sedan now offers a quiet, isolated ride worthy of dignified heads of state.

Just as one would expect inside a flagship sedan from a luxury marque, the Q overflows with sumptuous features such as power leather seats, wood accents, premium Bose sound system, driver's seat memory, automatic climate control, power sunroof and power tilt/telescoping steering wheel. This year, Infiniti also proves that it knows how to listen to its customers. The beautiful analog timepiece that adorned the dashboard of the first-generation Q45, and was replaced by a digital clock two years ago, is back. Additionally, the Q's full metal sunroof has been replaced with a power glass sunroof with tilt/slide, one-touch open and a sunshade.

Outside, Infiniti has touched up the styling of the vehicle by reducing the amount of chrome on the front grille, adding new high intensity discharge (HID) headlamps with Xenon gas bulbs and crystalline lenses, and introducing two round projector beam bulbs per side. The license plate finisher is now body-colored, the trunk has a power closure assist, and the outside mirrors have an anti-glare coating. New exterior colors for 1999 are Hunter Green, Aspen White Pearl and Titanium.

The 4.1-liter V8 engine is still in place, though some would be happy to see Infiniti bring back the 4.5-liter V8 that powered the sedan prior to 1997. Overall, though, the Q45 offers a nice ride that is perfect for cross-country cruising. If you are in the market for a large luxurious sedan, and are unwilling to fight the gremlins that habitually inhabit many competing luxo-cruisers, you owe it to yourself to test drive a Q45.

1999 Highlights

Several small exterior and interior enhancements have been added to the Q for 1999, including a new sunroof, revised front styling and the return of the analog clock.

A great car let down by small issues

infinitiguy,10/17/2006

My 99 Q45 is my 2nd. Previously owned a 93 Q45. Both Q's are wonderful cars and a joy to drive. My BIG problem with owning these cars is 1) extremely high rate of depreciation 2) VERY expensive maintenance and repairs - major service intervals approach $1000. My 99 Q has issues with warped brake rotors, driveline vibratons, steering shudder that return after being "fixed". Sensors go bad

Solid state luxury at its finest

jere H,05/28/2005

The Q45 is in a class by itself for above Lincoln or Lexus. From the moment you close the door the tight solid sounds tells you that this car is "solid". As for the interior the leather is the truly the finest I've seen in a car. The suspension and the comfort of the seats give a flawless ride on the roughest of roads. The Bose sound and extreme quietness of the engine and no road

Purchased my Q45 with 14,000 miles on it & now have 117,000 miles. My Q drives as well today as when I bought it. This car has better sex appeal today than when it was first introduced. It has a very sleek appearance for a relatively large sedan. It has been mine and my kids favorite car to ride in. I havn't had any major problems than normal maintenance. It is a

Bought this car used in 2001 with 25,000 miles. It has been relatively trouble free. Dealer gave me a set anniversary wheels because the touring wheels were warped from chroming (this is apparently a common problem, don't chrome your wheels folks). Trouble free but for a few annoying problems (front doors close too easily). Some body flex is noticeable, but no

Should I lease or buy a 1999 INFINITI Q45?

Is it better to lease or buy a car? Ask most people and they'll probably tell you that car buying is the way to go. And from a financial perspective, it's true, provided you're willing to make higher monthly payments, pay off the loan in full and keep the car for a few years. Leasing, on the other hand, can be a less expensive option on a month-to-month basis. It's also good if you're someone who likes to drive a new car every three years or so.
