I had the same leak. Whenever it rained, my trunk carpet would get wet and my spare tire tub would fill with water.

Guess where it was coming from: the tail light. Yup, the tail light. It seems that one of the plastic mounting things broke, so the gasket between the light and the body wasn't sealing well. I tried fixing the mounting device but that didn't work, so I got some RTV silicone, took the light off, spread the silicone generously around the gasket, and put everything back together. Voila! No more leaks!

Hrmmm. I thought about that too teuobk.. When I took my taillights out to tint them, I noticed how 2 - 3 of the plastic mounting tabs were broke off on soem of the lights. I epoxied (sp?) the platic studs back on, but I'm not sure how well they are holding up :?

Maybe I'll have to pull them out and re-seal. Mine doesnt leak that bad.. Not enough to fill up the spare tire tub or anything.. Just enough to wet the rear carpet in the corners of the trunk

I had my 10-disc changer on the left hand side screwed to the floor in the trunk, and I recently removed it so I could put my NEO there, but I noticed the carpet was wet like the other side, and I really dont want a $600, 80-gig MP3 hard drive sitting on wet carpet, so I think I'll keep it in the cab

The trunk leak is usually caused by a unproperly sealed rear window. As for Jeff'* problem with the tail lights there is a plastic airless welder on the market. I saw it a GM tolls catalog. I'll get you the address & part number for the club today at work for all who are interested.

Just want to thank everybody. I will give here all this info that has been on here.

Here'* a summary we used to own:

1993 Bonneville SE (170 peak hp)
Problems to 60,000 miles: Just broken radio and exhaust gasket.
Quarter-mile: 16.28 at 82.11 mph (100% stock) --> Approx: 0-60mph in 7.7 sec.
Fuel mileage: Approx. 23 mpg mixed city/hwy; 30.2 mpg in 85-90mph hwy driving!
Most rattle-free and tight car we've ever owned except the 2002 Camaro and 1995 Trans Am which are tighter --> we've owned/own '92 Lexus ES300, '00 Mercury Villager, '96 Bonneville */C, and '02 Astro

I have friends who have 380k miles on the original 3.8L motor and it still doesn't burn oil!

I own an 88 LE, she gets me around and no matter how much I love her, she'* a ****, I'm sick of the way GM put her together, so annoying how everything is a pain to replace. IF you're not gonna do any maintenance on her yourself buy it cause they run GREAT! however if you end up doing all the repairs on the car, don't buy it. I've had problems with dealers not even having parts for it cause they said they dont make em no more. Damn GM!

Everyone has answered all your questions, except one, so I will cover that:

No 6 foot tall adult will feel comfotable in the back seat of a new Bonneville. I can not speak for the older models. My ex-wife'* '94 seemed pretty roomy in the back, but my 2002 is tight at best. It seem that Pontiac took space out of the back seat to make the trunk bigger. The back of the front seats is "hollowed out" a bit, but it doesn't help that much. They might have taken an inch or two out of the front also. I am only 5'-10", but I wish that seat could go back another inch or two. Of course, that would make the back seat leg room even less
