Price check... do these maintenance costs seem right to you?
 

So I'm calling around today to get price quotes for my 30K mile service. (actually I'm at 33k). I've already replaced the filters so all I would need for my G37x coupe is brake system fluid exchange, transfer case, front/rear diff oil, and basic oil change.

The best rates so far I've gotten are:

brake system - 89.95
transfer fluid - 49.95 (tech said this wasn't necessary)
front diff - 69.95
rear diff - 89.95
basic oil change 32.95
____________________________
Total $333


The 2 dealerships asked for $450 and $477.


Should I go with the cheapest one (and the guy sounded trustworth, for what it's worth), or should I pay a little more with the dealerships?

And am I paranoid if I think the reason why some of the techs ask how many miles I have, whether it's too early to do services, etc., is because they want to charge me for services not done? Some of them sounded shady.

Wow, that's WAY cheaper than what my dealership is charging me. I also have a G37X coupe.

This is what I have not done yet on my car.

Lube locks/hinges - 19.95
tranny fluid - 199.95
coolant - 149.95 (Dealership said its dirty, looks really clean when I checked it.)
drive belt - 189.95
radiator cap 17.95 (Told me to replace it due to other caps losing pressure over time, I'm only at 30k)
transfer fluid - 89.95
both diff 219.90

Or their 30K service package is $850 which includes above an oil change, wiper blades, and both engine and cabin filters.

Told me that I needed to do all of these to prevent damages to my car. I'll probably do some of these but not all of them

Those are some pretty aggressive pricing there ...

im running out the door but heres a quick reply.

from what i've read, the later model 09 g37x have a blue coolant and are longer lasting. they dont need to be replaced anytime soon, just topped off maybe.

trnsfer case quotes were all over the place, with the dealership wanting to charge me 280!

dont know if i have to do the drive belt. im just going by the maintenance recommendations. but i do here a whirring, spinning sound when at idle. don't know if that's the drive belt...

if you call around im sure you can get it cheaper. the cheapest for me also has the highest yelp ratings, although 3 reviews is not a solid amount. plus the guy didn't sound shady. hope it goes well...

ok, so the last guy called me and offered all of these services for 253. that's severely undercutting everyone.
