I've got a M reg 1994 Cavalier 2.0 16v Auto Saloon, had it about three years, there were a few problems with the engine management system always cutting in but that turned out to be a faulty wire, however it is a pretty good car overall for the money, I bought it for £400. The CDX model is near top of the range so it has electric everything from windows, sunroof even elcetric heated mirrors, the air con needed topping up but once that was sorted it was fine. The engine although can be riddled with problems if you get a dud is fine and developes 136 BHP, it is pretty nippy as well with a 0-60mph in 8 seconds, in straight line speeds it is better than a similarly aged Mondeo however the Mondeo has better handling and also a better driving position, mine is 15 years old and not a spot of rust and still looks good. I have previously owned a Mondeo and I think the cars are very close although the Mondeo is overall a better car as it was designed about 6 years after the MK 3 Cavalier, however if I had the choice I'd probably go for a newer Mondeo however the top of the range Cavs are much better than the horrid Vectras that came along a year or so after.
