What is your mileage? I sold my 95 at 189K.

Navyguy, this is totally dependent on which model you have. Please put that in your signature!

If you have an SSEi, no worries.

If you have an SE, SLE, or SSE, you MIGHT have to replace the upper intake sometime. For longevity purposes, be glad you got the 4T60E trans

so far ive caught leaks in my firewall (where the wires go into the car on the passenger side, sunroof drains, taillights and all doors weatherstriping. i did get it all fixed, but it took a while to find some of em

Ive replaced my water pump and my dampner pulley/tensioner pulley (luckily I had an extended warranty at the time) But other than that the standard GM alternator problems and water pump problems (ive replaced the alternator and water pump in all but 1 of the 5 GMs ive owned, but luckily most are easy 2 do and the parts arent 2 expensive, if you are going to replace your alternator then get a brand new core not remanufactured most new alternators have larger bearings in them and they have fixed all the design problems of the originals.

Thank you everyone for the pleasant welcome and the information on my car. You all we're a great help.

Before you go...please update your vehicle info. As Bill (wren) stated, the L67 (supercharged) Bonnevilles are as solid as they come, coupler runs around $30, Harmonic balancer runs around $270 installed. The L36 (series II Naturally aspirated) have the potential for upper intake failure, I don't know what that part runs installed, but that would be the biggest hit you would take, the rest is all good.

Welcome and take care, and thanks for serving our country!

All im waiting on is for my dad to send me the title. My dad seen it, and got it for me. All i know is that it has 173,000 miles on it. Is that bad for this car? I know alot of cars can't take that many miles.

First thing you'll want to do is put a drilled 180* thermostat in for continued longevity of the motor. Other than that if the motor and tranny are working great just keep the maintenance up to par (tranny flush, coolant flush, and oil changes every 3k miles).
I had over 300,000 miles on my 1992 Bonneville SE when it was rear-ended and it still was running it'* original motor and trans in excellent running condition.

Okay i got the title. My dad was wrong, its a 94 se. With 173698 miles. Can anyone tell me anything about this model. And if it has the same problems as you told me before. And should i worry about the 800 mile trip its going to take. Its in excellent condition, the person before me, took really good care of it. Maybe that will help some. Any information would be appreciated.

1994 -Good. The intake manifold problem is not as serious for this as the 1995. The biggest problems you might find are the trans issues which were mentioned above. Might have an issue with lower intake manifold gaskets, but that'* not nearly as dangerous as the cracked upper intake on the 1995-newer 3800'*. Just check the oil every time you fill gas (or every 1000 miles at least) and if it'* low check where the manifolds meet the heads and if you see oil or coolant residue it'* due. This is somewhat common, but not as often as some might think.
