l was looking at the coupe but the repairs look a little pricey...is it the same with the sedan?

As much info as possible would be extremely possible...thanks

well to start with, if you goto the dealer, you will be ripped off.
you might get a good price on an oil change, but brakes.. yeah, well, a dealership brake job will run you $400-$600.
You have an Infinity, considered a luxary car, you will pay more because of the ''luxary''.
an oil change avg would be $35, plus taxes and environmental fees.
brakes at a regular shop would be like $200.

Go to edmunds.com and look at the cost to own record for a G35 sedan.

For oil changes, l pay about $75, for Mobil 1 at the dealership.
The 30,000 mile service runs about $800 from the dealership.

l have not had to do any brake work on my coupe yet. As much as everyone says the Brembos never last mine have gone 23K miles with plenty left, luckily.

l am pretty sure there are not any big differences in costs for the sedan. The only difference in cost my dealerships lists is the 30K service is an extra $50 for M45s

Poli, next time u go for an oil change, pick up mobil one synthetic from wal-mart. then the dealer will only charge u 26 dollars or something for the oil change. (6 for the filter & like 20 for labor). Mobil one oil is only like 21 dollars at wal mart.
Grand total ~45 bucks.

Oil = 45 dollars
15K service = 275
Tires = 800 + install (50) (you will be lucky for 20K+ out of these)

Have not hit the 30K mark on either of my cars yet so dunno if the 30K service is more costly.
