Which would you prefer & why?
 

Cadillac Deville-DTS / Buick Lucerne / Park Avenue?

Anything with the 3.8 are very solid engines, once the UIM/LIM's are done. Offer good fuel mileage and longevity.
I'm a Park Ave guy, wouldn't mind a second one in "Ultra" trim. S/C !
Room under the hood to work on them, receives bonus points too.:D

2008-2011 Buick Lucerne Super. Northstar V8 L37 (292HP/288lb-ft) and mag-ride suspension

I agree art, im a park ave guy myself! And im actually trying to find a clean one in Ultra but i live in Wisconsin so the ones that r clean get snatched almost as soon as forsale goes in the windows.. So im starting to get the idea of buying a jackd one and put the money into it and pretty it up... As long as i can find one with minimum rust under her everything else ill take care of with the junk yard and a paint shop!

Ive also been starting to like the lucerne! But i dont to much like the interior in them.. Or maybe they have different styles inside the few ive seen didnt attract me toward it much..

Be patient and one will come your way that is clean, lower mile hopefully too!
I know what you mean about getting snapped up..These cars are sought after and dont last long on CL or lot for that matter. Hope you find what your looking for.
How much smaller is that Lucerne inside? All I know is with the Pk Ave you got tons of leg room. The trunk is great, and if you got kids, it's even better!
If they don't shut up you can threaten them that the trunk is next..ha ha..:)

Park Avenue of out California, Arizona, Texas, Alabama, etc. They are out there.

Thats the same thing my brother said but its true! N yea they do! But i can say after having the PA for so long.. It is a very noticable difference on space.. Leg room and the overall space of the inside of the car.. But its still is kinda roomy if that makes sense just not as much as the PA.. Trunk is still pretty big tho... Lol thats something i would do say! Lol

Ya kno i actually didnt think of that! Now im about to check for one out in those states! If one has low enough miles.. The wife took vaca around my birthday so it could b a road trip for a new PA :-) "kinda getting excited already! Lol"

My vote is for 97' or up supercharged PA, great reliable cars, safe, and comfortable to drive on lOng trips.
