Thread: Should i move to the grand prix world and get rid of the grand am gt?

Dont get a grand prix GT.
GTP or bust, unless 04+.

Either grand prix can get good mpgs.

The supercharger is really not something that goes bad, the coupler inside can wear out, but its a simple fix.

And with any car, the faster you go the worse the fuel econ. Going 70 instead of 80 would prolly be 3-5 mpgs better.

I know I can get 30-32 at 70, but only mid 20's at 80.

A little more research on common issue's with the Grand Prix will help you alot in figuring out what you may want.

dont go 04+... not with your budget anyway.. FWIW I drive 30 miles a day almost all highway and I can get almost 400 miles to a tank of gas. Depending on how much blower whine I wanna hear that week. The fact that you have to run premium does not really mean THAT much.. It is only like 3-4$ more per fillup.. It averages out to like .20 cents more per gallon most of the time.

Well when I had my GP GT I was getting on average 26mpg on the highway with the GTP I could get closer to 30mpg @ 80mph.

I would try to get a GTP if your going to get a Grand Prix the GT's aren't really worth what people try to sell them for. There aren't really to many advantages over the 97-03 and the 04+ cars other than the 06-07 cars need to have a different pcm put in if your tuning and the 08's from what I hear can not be tuned at all. The 04+ cars have slightly better transmissions and hardened connecting rods in the engine and the 04+ supercharged engines are more power efficient than the 97-03 because of the Eaton M90 Gen V supercharger.

And the failure rate of the superchargers are very very low, the rest of the car could fall apart around those things, the only thing you really have to worry about is the coupler wearing out but that is a cheep and easy fix ~$30 if you do it yourself.

Dammit cam you ninjad me.

You are going to get a lot of naysayers who will crap all over the GAGT. Personally, I don't mind them. I've always liked the body styling of the GTs, and found the interior surprisingly roomy for the car's size.

Given that, I would not fear switching to the 3800 as far as repairs. Most repairs are fairly easy, and there is certainly an ample amount of info on how to fix just about anything on them by now. As for MPGs, I can get slightly above 30 on the highway when just cruising at 70 - 80MPH in my GTP. I'm averaging about 22 - 23 MPG only taking the expressway TO work, and city streets for coming home and everything else, and that's with a bad MAF. I am just shy of 171k miles on the original motor, trans and supercharger at the moment, and sometimes the engine is running so smooth at red lights that I think it shut off on me, so I would not worry about the s/c going out on you. Even if it did, it's relatively cheap and easy to find a Gen3 M90 these days.

As far as Gen 6 vs. Gen 7 body style, it will mostly come down to personal preference. The Gen 7 will have much more comfortable seats, and the interior in general uses slightly better materials. You also get the Series III motor with 20 more HP on the s/ced model. They also didn't gain as much popularity/sales new as the previous generation did, so you can get a '04 or '05 for about the same price (and sometimes cheaper) than a '02 or '03. If you go Gen 6, make sure you go '99+. There are little annoying one off things on the 97s/98s that are different than the rest of the years (i.e. PCM, MAF sensor, etc).

Switching from a 3.4 to a supercharged 3800 will be the best thing you've ever done in your life.

I personally think the GP is a better car than the GA. The 3800 v6 is a very well built engine that has been known to last over 300k miles. As for gas mileage, I thought the GA would do better since its offered in a 4 cyl. My 2004 averages 24.1 MPG, however, on a recent trip i reset the meter. On interstate only and cruising at 83mph, i was able to averge 30.7MPG.

I like the look of the 2003's soooo much better than the 04+, but when I was car hunting I didnt have a specific car in mind. I bought mine for $4000 back in January. It had a complete maintenance record and 199,000 miles on the clock. I am now up to 218,000 and I just replaced the water pump and power steering pump, both were original.

Im 6'3" and theres pleeeeeenty of room and i dont even put the seat all the way back. Every car is gonna have its issues, but search, read and try to do preventative maintenance and youll be fine. These cars are all around great cars. I can guarantee that if you get one, youll thank us! But do yourself a favor and get a gtp and dont buy one thats modded or beat to **** and you should be fine.

to add to this at 55mph i can average 35 to 45 mpg, but i hate driving 55
