I am looking at 2005 model year Pontiac Bonnevilles (base model) and Buick Lesabres. What are the mechanical differences, if any, between these if both are "H" bodies and "K" engines (non-super-charged 3.8L V6)?
The suspension feels tighter on the Bonneville, so I guess i might have different springs or shocks. Is there a transmission gearing difference too?
I pretty much think the engine /trans gearing are the same in the LeSabre as the Bonneville. Both have 205 hp, same as my Park Avenue. The radiator hoses on mine car say LeSabre/Park Avenue/Bonneville.
I take this to mean Impala/Monte & GP (3800V6) hose's would be different.
Yes the suspension & steering in a Bonneville will be a bit firmer & tight than the Buick. Tire width might also be a bit wider on the Pontiac. I think the battery is located under the rear seat on both these vehicles.
Good Luck,

Yes the battery is under the rear seat in both. I checked.

The battery is a bit more expensive than most too, but they do last a while. I replaced mine after 7 years just because it was going to be getting cold and I'd rather do that sort of thing in mild temperature rather than 10 below.
