A week ago bought an 04 Coup'e. Spent a few days checking her over and have ordered plugs filters and oil, all to do this week. Did my usual with any new purcchase, ran it outta juice put in a fresh gallon and that returned me 28 miles untill it "coughed" for more. Q?= would this be an average or below for a 98,000 mile '05' Xfire ? She runs sweet but, as yet i havn't heard that kool throb from the exhaust so maybe someones changed and quietened down from the original ex system.a lotta surface RUST underneath,to be cleaned up and then Duck-oiled or Undersealed. ALSO have new rubber bushes on way to fit as I don't seem to have much ride comfort (just a little too rigidly bumpy for me). She sailed thru our MOT TEST with only a couple of ADVISORIES, 1 coil spring corroded, Park brake needs adjusting and mentioned the underneath Surface RUST ASWELL!!. Have all new brake pads on way to fit,also calipers to re-furbish using Copper grease and Red Rubber grease on the boots for weatherproofing, as I don"t want any more RUST in the lower regions. Any and all other Care Advices are welcome.Happy Days All, CHEERZ !!

 

Welcome to the Forum. Good luck with the repairs and servicing of your Crossfire. Regarding the ride (I don't seem to have much ride comfort (just a little too rigidly bumpy for me), the short wheelbase is the culprit. Throughout the forum in various discussions the ride is negatively mentioned. After all, it is a sports car. (Sports cars are designed with performance the priority, while regular cars focus on comfort, practicality, and efficiency) That said have fun! -CFK

Welcome to the forum! There are a couple threads every new owner should be aware of. You can find them in the TSB and How to Article section: Index of Crossfire problems and repairs and Crossfire Documentation Collection: Click this Link

Your 28 miles is about right. On long trips in the States with speed control set at 72 mph I can squeeze 32 mile per gallon out of my Limited. In the city I get about 28 mpg.

The Crossfire came with a rubberized undercoating in the wheel wells and some of the exposed under body, but the control arms on the suspension are not coated.

I prefer the stiff ride of my cars and have actually made mine stiffer than OEM so the car is more stable while winding through turns in the mountains. Softer riding springs and shocks are available and you can use a bite more rubber in the sidewalls of the tires to help soften bumps/pot holes, but you will lose stability with the softer ride. Be aware there is not much room to play with in the front to use higher ratio tires before you start scrubbing the wheel well, however the rear is more forgiving with a bit more room. Have fun.
