I don't know how many miles you have on the Civic, but I doubt you will recover most of the money you spent on mods. The G37S is a luxury sports car. I get about 20 the way i drive and you need premium fuel. If you're getting a manual, I would be concerned the clutch would soon need replaced. To test the clutch drive the car in high gear (on the highway) and floor the gas. If the car takes off, everything is fine, if the clutch slips you should hear it or see the tach jump.

Other than that, the steering wheel has a tendency to get worn where the switches are, that part can be bought for $30 on eBay. The door pulls get scratched. I had to replace my grille because the chrome peeled across the top. A 2008 with 49,000 should have a few months of powertrain warranty. This wouldn't cover the clutch, but everything else should be OK.

Bottom line, an Infiniti will cost more than a Honda, but IMO it is worth it. $21,000 seems like a good price.

 

fuel costs will be more with the G37, bottom line. preventative maintenance will be roughly the same, assuming you don't go to the dealer for routine services. if you DIY or go to an independent shop you won't see much difference - it is just a Nissan after all. all parts are Nissan parts. items like tires will be more with the G37 as well. the G37 is a reliable car so go get an inspection done and you should be good to go, if you can live with the fuel costs...

 

If its an ester oil car it will be expensive to maintain.

 

Stay with the civic. Cheaper to own. Cheaper to maintain. Cheaper to mod. Better as a DD.

 

cost wise stick with the civic. if you are ready for a more mature and luxurious car get the G. it will cost a lot more to maintain and modify but the vast difference between the 2 more than makes up for it.

 

Not even a real question when you think about it ..... the G all the way. BTW .... you don't have to stick with ester oil, everyone switches to synthetic.

 

Thank you all for the helpful comments. I am split 50/50. I want more luxury, and a nicer ride than my Si. But, I love having a quick , nimble car (SI) that does pretty good on premium gas. I take trips sometimes (6 1/2 hours) travel in my Si, and it is good on gas, just not super comfortable with a Sport Suspension. Also, I will use the G as a daily driver, as I do the Si.
I am also buying a new house in the next couple months, so it seems the wise choice is to postpone the buying of the G, but I loved it since I test drove it...

 

The G is pretty quick and nimble ..... I took my wife, daughter and luggage on a trip from MD to MI and I got almost 30mpg out of it, all depends on how you drive it.

Basically sit inside your Civic, listen carefully and then close the door, now do that with the G .... you will see the G is so much more of a refined car than the Civic, it's a Civic.

 

Never buy a car before a house...it will drop your credit score and could prevent you from getting financed.

It seems more like a matter of time for you. The question isn't do I choose an SI over a G, the question is when do I make the transition.

BTW, you get what you pay for 99% of the time. Beware of 'good' deals

Deals come along all the time and the G's value is likely to drop in the next year due to the new Q models. I would buy the house and chill on that for a bit and then make the move to the G in about a year.

 

It is all about how you drive it sir. Civic of course has better gas mileage for having 4 cylinders instead of 6. However g37 is much sexier looking car that will turn everyone heads! One more thing, it is very hard to resist flooring the car and there goes your gas mileage

 

Thanks you very much Dgglr for the advice. I know, I have to wait until after everything clears with the house. Thanks for the heads up about the new Q models.

 

Exactly what made me choose my G over a new si/ms3

 

I'd say stick with your Si....after reading all the quotes and the 50/50 views of your own OP your not sure...
Having a S6 before my G and making my own switch is the best thing I've done.
Best of luck!

 

Keep your car. Get the house sorted out first. Fuel is punishing on this car. 18-22 MPG requiring premium and 16-17 gallons per fillup will get costly fast. Especially with gas at $4+/gallon.

Mods are expensive. There are vendors that sell two mufflers and a few inches of pipe for $800. That is probably a full decent quality catback on a Si.

 

Thanks man. Yea, fuel is pushing $4.00 a gallon now, and that is scary ! I don't worry when I get on my Si and redline it because I am still getting 25-30 miles on it city/highway. A full new catback on the Si, can be had for $625.00 , and that could be an Apexi or Tanabe. I'll just wait on the NSX!

To answer an earlier post: I have 109,000 miles on the Si, and with the tune it is running very smooth and quick.

I also have to say, almost all the responses I have gotten shows the the G owners are class act people. More mature, and have been very helpful with few snarl remarks about my Si. I want to say Thank you and many props to the Class Act G owners. At times, on the Civic Forum people bash people without an Si, and write negative comments. I believe possibly the Si owners are younger, and this is the one of the primary reasons I am considering the G. I am approaching 40 years old and still rolling in the Si!
