Bought this GXP in Feb 2005; actually bought it for my wife; not only does she love it , but I like to drive it; I grew up in the muscle car era and this reminds me of it. Love the Northstar V8. The car has been very reliable with decent mileage considering the power available City 14.5/Highway about 23. Love the HUD, memory driver features(seats & mirror, plus radio. Ours is Black with Grey interior; it's a real head turner. The car is garage kept and has very low mileage (driven to/from grocery store by a little old lady; we are in our late 60s). Her previous car was a 1996 T-Top Camaro RS, with 3.8L V-6, also low mileage, 10 years, 34,000. We plan on keeping the GXP a Long time!
To start, I love Bonnevilles. I owned a '98 Bonnie all through high school and college and it served me well. Bought this GXP once I graduated, and its definitely a love-hate relationship. As far as style, this car has it. Interior, exterior, handling, performance - all fantastic. However, the biggest issue I have with this car is the reliability. I bought it with 64k on it and in 2.5 years I'm at 83k and have put over $8,000 worth or repairs into it (I have a warranty). There is no way that it should need this many repairs when its just a daily driver with less than 10k a year.
So far owned for 3,000 miles. I got this beautiful car for a bargain price with 90k miles. It drives like it has 30k miles. I've gotten between 23 and 27 mpg per tank so far. Nothing has broken except for a burned out head- light bulb. Very smooth torquey engine with silky smooth shifting transmission. Lots of style. More style than all the imports for sure. I love the look from the back and side especially. Only cool Chryslers and Dodge's have more style but they are troublesome. This car feels heavy and well-built and safe. Nice looking interior with a large trunk and back seat. This car is big and a bit tricky to maneuver in parking lots and city but its a dream on the freeway.
This car is great. I bought with 90K. It now has 102K. I love the style. Very stylish car. Its big!! Its comfy. It has a very quiet cabin. The gm 3.8 is an amazing engine. Actually got 30 mpg when doing a highway trip of 480 miles. with 16 gallons of gas. It has a big gas tank at 18 gallons. Don't need to fill up much. Normal MPG is about 25 with highway/city mix and not winter out. One problem it died on me on the freeway. Kinda scary. It was the Mass airflow sensor. It happened out of nowhere. No engine lights. I would replace this at 100k miles or sooner. That's when it died on me. Besides for that no problems. You can probably have autozone replace for you.
Bought an 01, SSEI, and loved it, accept that it was white and showed every bug in Ga, Al, & Miss. BUT this GXP with V8 is a Blast. I can enjoy riding around and listening to these big 8 cylindars. With DOC and 4 valves/Cyl. this car will kick ass. The super charged 6 on my 01 was quick, but this is 1.5 seconds faster. I am burning mid grade gas, and not getting the same mileage HWY or City, but the wasy it drives and sounds, it is worth it. do yourself a favor, test drive one.
