2005 Cadillac DeVille Reviews

i have a 2005 deville with over 221,000 miles. we bought this car new and i have to say it has been well worth the money. i've never had any major issues with this car. i've had routine maintenance done, such as brakes and such, and we change the oil every 3-5000 miles and had the transmission flushed about every 60-80,000 miles. i use synthetic oil and swear by this oil. i've had to replace the a/c compressor once, the alternator once, battery once, 2 coil packs and a coil rail, and a wheel hub. other than that i guess i've had a pretty good car. i have to add 1 quart of oil about every 3000 miles which i've been told is normal. i am starting to notice a shifting problem and now that i have read up on this, it must be a typical problem. i used to take my car to the dealer(rip off) for regular maintenance when it was under warranty, but when that ended at 100,000 miles, i take it to my local repair shop. not everyone wants to work on these cars. my mechanic has been great and honest. hard to find nowadays. i just replaced the original spark plugs ( yes, i said original). why fix something that's not broke. i probably could have went more miles with those, but i figured it was about time. everyone around my town tells me that the north star engines are throw aways because they cost so much to either replace or repair and they usually don't last over 120,000 miles. i guess i picked a good one. i will buy another one if and when i have to. i'm worried tho that i won't get as good as one as this one. p.s., i also have an 03 chevy silverado truck with 285,000 miles on it.

I have a 2005 that I've driven for 167k miles with nothing more than brakes and tires to be changed. I change the oil about every 4k and mainly run on highways with the cruise control. Best car that I've owned.

this car is 2005 deville with 30.000 miles on it. it has been taken good care of oil changed every 3.000 miles it looks like new fan motor wont shut off useing oil tires wore out Its nota good deal for 40.ooo thousands doller car no wonder toyota and foreign cars have taken our market olds was the best car GM made
