Since I purchased the Q45 several years ago all service work has been done in a timely manner.The finish has held up beautifully since I keep it polished. This is a sweet 4 door sedan which competes with the Lexus LS 430 but costs thousands less!

A great car let down

Vehicle: 1999 Infiniti Q45

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 on the car and it costs $$$$ to replace. Example: O2 sensor (this car has 4), fixed one for $365. Knock sensor (one of 2) requires COMPLETE intake removal @ $1000. Turbine sensor leak cost $2300 to fix. It never ends. I agree with all the other reviews on this car, but 1 have had 2 Q's that cost $$$$ to keep

Best bang for the buck

Every bit the car and more than the Lexus LS series but almost half the cost used. I never understood how Infiniti botched this market share, it certainly is not due to quality. This is my 2nd Q. The last one had 110k miles before anything major started to appear.

Love it

I've had this car a number of years now and I'll never buy another brand of luxury vehicle again. Aside from regular maintenance my car has never had to have any major repairs. Build quality is excellent. Design inside and out is classic and it's one that will never go out of style.

A winner

Bought this private owner. I was worried about the V8s gas mileage but not bad if you keep your foot off the floor. Most comfortable vehicle I have ever driven or rode in. I am in sales and LOVE to take clients in this awesome ride!
