We got the car in April 2008 with 60k miles. My wife has a 70 miles commute every day, so we are putting a lot of milage on the vehicel. Plush ride, very comfortable. However, every 4 months or so there had been issues - mostly with the electronic. Every visit in the shop is at least $700. No wonder that you can by those used ones so dirt cheap - you need to invest $3,000 or more every year just to keep them running! Gas milage is about 19 MPG on premium gas (the poster who reported 30+ miles is clearly smoking something!) with a mix of city & highway.
I think that the devilles' are good sized cars that eliminating any cramped feelings that most other cars can have. This is a definite upgrade from chevy division products, and I am sad to see the company changing it's product line up into unfamiliar territory. Being a 2002 deville I have made and paid for some repairs which isn't fun, but eventually any 10+ year old car is going to need some work done to it. I am still a little confused to what Cadillac thinks that they are competing with at the same price points of everyone else. I think that the build quality of cadillacs should be the standard for all GM products instead of them continuously pumping out tin can crap to consumers.
This is a great riding car and a looker, too. BUT: last year at 73000 miles I had to get oil pan gaskets replaced - $1300. Last month at 83,000 miles, the northstar has a leaky head gasket. That'll be another $1400 plus. Sad that such an expensive car develops problems so soon. I've driven Buick lesabres passed 160,000 miles with no such problems. This is my LAST Caddy.
This is my fifth Cadillac and will probably be my last. It was supposed to be a Certified Pre Owned vehicle but within a week, it was in the shop for three weeks. They had to replace the dash and auto headlights (they are still broken). The traction control can not be turned off (they say it's a computer prob, but can't fix it), there is a pronounced vibration at over 60 mph (the shop says its a characteristic of the car and they can't fix it), and a host of other small problems. I bought the car because it was certified and am sorely disappointed. I always liked Cadillacs but their customer service, at least at my dealership, is horrible. They just don't seem to care one whit. They've sold the car now so to heck with the purchaser. Sad, ain't it.
this is my third cadillac and from my expierence, its all a roll of the dice! some are built to last with minimal repairs, and others will make you pull your hair out! routine maintenance plays a critical role of the life of your caddy, used caddys should be bought will eligible extended warranty, if buying used check gm inquiry report and that should tell you alot about your caddys reliablity. the car overall is great, i guess for me the third times a charm, ive paid my dues to cadillac, do your research, inspect your caddy daily, and keep up with routine maintenance.
