Yes Andrew, they do.
I dont think that the XM is as addictive as the CX was but its probably more practical. My last CX went through a head gasket every 15k and when you consider I ran it for over 150k - that's dedication. I still consider it in many respects the best car I have ever owned. I only bought my first one because of the refinement of the diesel engine, I knew little about the car, but I hadn't driven it for long before I started to appreciate the superb directional stability due largely to the central steering knuckles, the diravi steering, the ride comfort and the huge load space in the estate, and it was much easier to work on that the XM.
On the downside, the heater was next to useless, 1st gear was far to high so you had to do a lot of clutch slipping to get away, although the clutch lasted for about 200k, and you had to adjust the handbrake about every 15 minutes. The head light were good though.
The XM on the other hand, has an excellent heater, is geared just about right and has brilliant fuel consumption (2.1 manual) It doesn't drive like a 17' mini as did the CX but it does have a nice comfortable interior.
