42k? Yikes

Most GXP'* I've seen listed lately on the continent are under 30, or barely over.

Go with the Crimson Tintcoat, but I am biased. Post when you finally purchase the GXP.

I would go with that color too. I was gonna get a marauder and I am glad I didnt after reading what you say. the bonneville will rin fine on 87 but you will definatly notice a performance drop at higher speeds. If the dealer is letting a fully loaded GXP go for $30,000 sounds good you probably could save a grand or 2 off that price.

Good luck to you sir.

Be careful if you ever have to get gas out there other than the base. Always make sure it is a good looking gas station, hopefully a reputable chain and such. I got gas from this one place downtown once and boy that was a bit of expense to have the fuel system dried out, guess it has a buncha water in it or something. I know that Chevron on the island is a bank account nightmare, probably the best station other than bases, is like Aloha or Tesoro or something like that. Just a tip.

Yeah I would reccomend putting at least 92 in a Northstar.

New Northstars can run on 87. Many people keep thinking of the older northstars that required 91 and up. All fuel grades have the same cleaners in them so you will not have a problem.

Dont waste money of fuel if you are just going back and forth to work etc. Like I said previously if you want better high speed performance get the premium fuel but for all around regular driving 87 will be safe and fine in that car.

Only thing is you are also hurting the engine over time with regular.... predetenation is muffled with the preknock sensors BUT.... I will repeat, the owners manual states the required octane is 92 and for 16 cents a gallon in my area, I spent 30 grand already and dont feel the extra $3.00 a fill up is to much to give the engine and what all the sensors and OEM tuning are looking for. Shadow, did you run premium gas in that video you posted. If not I think you will be pleasently surprised how much better engine will do after you run a tankful through and try again.

Gas prices: Pretty bad all right. Premium'* up to $3.25/gal out here...
I paid $26,000 a few months ago (with $2000 GM card discount), and I heard others got even better deals. I'll bet you could do better, especially if he wants to sell it more than you want to buy it.

Premium is knocking on $3/gal here in MI, but the gas price can't mean that much to you, where can you go?
I'll drive mine about 24,000 miles per year. The mileage and Premium gas will probably cost me an extra $1500/yr over the Impala. Reality sucks, but what a ride!

Surprisingly enough, my daily commute is about 50 miles (there and back). Since getting the Marauder off the ship in mid-September, I've gone from 33,800 to 40,750+. Lotta running around to do out here, and we live pretty far out from the main city.

Although...ya know, I wish there was an interisland ferry in this state. I hear driving on the Big Island is kinda fun; the roads there aren't nearly as crowded.

Decision day is tomorrow! We will see...I finally got the Marauder patched back together; only thing missing at this point is an alignment... What will hurt on the deal is that I'm about 4k upside-down on the Marauder, so that'll drive the price up a bit.

Yeah GXP that video was with mid grade 89. Our newer N** has knock sensors that retard the timing to adjust for reg gas. I have driven with 94 and back to 87 grade gas and yes you are right its a night and day difference. My owners manual said 87 is fine but for maximum performance use 91 and up.

I guess what it comes down to is what you can afford at the time.
