Hey everyone. My name is Josh, and I thought I'd better join up on a forum about GM'*, as I just picked up a 2005 Pontiac Bonneville GXP.
I did research ahead of time, and generally just assumed the Northstar platform was pretty solid, so I'm not all that worried about my car, it seems pretty solid so far. There are of course a few issues.
This one has two problems I know of, it leaks oil, and that is getting onto the exhaust and wafting into the cabin whenever I come to a stop, and the LED'* have started to go on the dash, it'* not too bad, the "D" drive indicator light is out, and one on the radio, so I'm not that bothered by that much, it'* not too intrusive.
Exterior, some loose trim in the rear wheel well on the driver side, and hail damage, with a scuff or two from who knows what here and there. (Didn't know about the trunk leak, still have to check that).
So, in the coming days here I might ask about the oil stuff, so far as I've seen the most common cause seems to be some oil lines, hopefully that'* what it is. Everything else seems dandy at the moment.
When I bought the car, the average fuel economy was around 15.8 L/100k (15 MPG). Since I've been driving it (mostly in the city, but later at night) it'* now sitting around 11.4 L/100k (20 MPG) So, that sounds pretty average, and based on that I figure the engine must be in fairly good shape. The instant fuel economy readings on level ground at about 80 kph (50 mph) reach 7.5 L/100k (30 MPG). It is incredibly hard to drive this car economically... the sound of that V8 is intoxicating. I haven't been this thrilled with a vehicle since my old Mustang GT, and this Bonneville offers so much more than what the fourth-generation Mustang'* did.
I look forward to being here and talking Pontiac'*, here'* a few pictures of it:
I hadn't washed it yet... I've done so now and will update with new pics when it'* not 12 AM! As you can see, the exterior has seen some action... hail sucks. But the price was right, and I'm convinced the power-train is solid... or so I hope. Earlier when I started it this evening it was a little rough for a few moments, but I've seen behaviour like that from a lot of vehicles.
I knew about the oil problem before I bought it, my dad advised against the purchase, but a couple years ago I rebuilt a Subaru 2.5 engine from the crank out after a head gasket blew and cracked the block, so I'm not really afraid of having to spend some time in and under it if need be.
