My friend is selling his 05 G35 coupe. 47,000 miles. Pretty good condition. Only issue with this car is about 4,000 miles ago, his engine was replaced under warranty because the former engine burned an usual amount of oil.

Will this hurt the value of the car or its resale value in the future? I just want to know a fair price I should offer him for the car.

i would consider it a blessing bc its very common for that to happen in the 04 & 05's. i'd just pay what ever it books for in your area. assuming he broke that engine in properly of course

As warranty work, I'd say it doesn't hurt the value of the car at all. I'd happily pay Kbb value for the car knowing you basically have a car with 4k miles on the engine, assuming the engine was brand new when replaced.

Having oil consumption bad enough to warrant a replacement engine is not "very common" at all, it isn't even that common if you look at overall numbers of how many revup engine g35's were sold.

maybe so, ive just seen this more than enough to say its common. (i work with a used car lot some and so i try and drive all the G’s they get) i was goin to get an 05 but didnt for this reason. where it may not be "very common" as you say - it was a number substantial enough that i didnt wish to risk it. thats just my take.

My cousin is a tech at Infinti of Santa Monica. And yes it's common. Problem is, most owners don't check their oil.

So it's up to the dealer to either tell the owner if the cars needs to go through an oil consumption test, or they just top it off and call it a day.
