Thread: thinking of switching to bonneville gxp. pros/cons?

Ok so im thinking of selling the gtp and going to a 04 Bonneville gxp. Some of you guys know those cars better than i do so id like some feedback on them...besides bigger motor sucking more gas. What are some common problems to look out for?

i would love to switch over to a GXP but dont have the money, i personally like the Bonneville GXP better then the GP GXP but thats just my opinion if you get it have fun with the V8! im not sure what problems they might have alot of the problems may not have been found yet considering they are still kind of a newer car. you would have to hear from some of the GXP guys on here

the only upgrade i see is being more comfortable in a bonne gxp. v8 mated to 4t65- youre gonna have a bad time. its slower than your gtp. doesnt get very good gas mileage. im seeing reviews and it looks like the average is about 21 on the highway going 75. lol. the engines are DOHC so they are harder to work on...pretty sure its a northstar?

Bonne GXP has the 4.6 V8 with the stronger 4T80e, I think.

if they are northstar engines stay away lol but i dont think they are

its a northstar

yup its a northstar

well thats a con: its a nothstar

Pros: None

Cons: Everything

Stay away from the gxp Bonneville. It's slower than the l67 bonnies

Nothing here worries me. I was looking for things like cracked heads, cam(s) timing, rod or main journal issues etc. You know the stuff that is out of my realm or will be overly expensive. Can you direct me to another forum that's verse?

If you have a junkyard near your house...go visit it. You'll find a ton of caddies in there w/o a single scratch on the body. The reason being is they have northturds in them. The head studs, gaskets and heads are prone to issues. The head bolts are in aluminum....right. The kit to take it all apart and fix it is $2500ish all by itself w/o labor. The motor is huge and there's no room in the bay to work on it.

No junkyards will sell Northstar motors used. They have learned that it's not worth trying to sell one because they are all junk.

They aren't called sh1tstars for a reason.

Just google it.

It ain't hard to find plenty of issues.

Also, have you ever seen a more confused interior finished car in your entire life?

Plastic, Aluminum, Carbon Fiber, Leather, Suede, and other brushed metals?

The lulz.
