I bought this car for very cheap used. As I was short of money at the time but still wanted some power this was very enticing. The 4.5 V8 has a lot of get up and go. the suspension is quite soft so it usually feels like you are accelerating faster than you really are. For me, the engine has been very reliable. There has been very few fixes and none too serious. That being said, this is not an easy car to work on. there isn't a lot of room under the hood and if you have gorilla hands as I do it can be pretty tough.
This car really shines when the interior is considered. After being spoiled with such comfortable seats for a long time any other car just isn't as nice. I stand 6' 3" and sit comfortably in the front and back. The seats are very plush and everything feels like solid construction. Overall a great car. I have fallen in love with older Cadillacs.
Im approaching 200k and still going strong. Love this car
When I bought my 1990 Cadillac Sedan deVille in 2000 it had about 101,000 miles on it. It now has about 198,000 miles on it. With the exception of the parts that eventually wear out, it has been the most reliable car I have ever owned. It still gets around 28 MPG, (it got about 30 MPG when I bought it). The only complaint I have is the accessibility of the spark plugs but that is a moot point when considering the amount of I've spent on maintenance.
One sweet car. I average 25.8 miles to the gallon. Preventative maintenance is key. I clean my injectors and throttle once every six weeks. I simply remove the air filter and spray about half a can of throttle or fuel injector cleaner inside while the engine is running. My car idles flat/no misses. I spray inside the PCV valve, also. Brand new ACDelco throttles are available on ebay for $99.00. Relace motor mounts to restore engine performance. Keep the EGR valve clean or replace and only used distill water for coolant changes. I have 145,000 miles on mine and it performs and rides great. Ensure all vacuum hoses are leak free and on tight. This car will last 250,000 miles easy.
I like Cadillacs because they hold up well. I have owned 3 and all three have done well. One went to 100,000 miles with only a exhaust repair and fuel injector repair. Now as far as foreign cars. My BMW 5 series 99 model went to 100,000 miles and by that time I had spent over 7,000 dollars on repairs, not including normal maint! Same thing happened with a Jag I owned. These foreign cars also cost more to own, purchase, so don't go telling me they are cheaper and hold up better. Regarding my now gone BMW, yes the engine and ride was great, but everything else was junk after 50,000 miles. Those are the facts I learned about domestic and foreign cars I have owned.
