The Bimmer is a bit too tight inside and commands a hefty premium for the name.
Not sure about your country but here looking at a comparable X-Type and a 325Xi they are really pretty close in price. The BMW's bring a lot more money used especially if you compare the two with high miles.
If I had a choice between the X-Type and a comparable BMW even if it was only a RWD and the two were the same money I would take the BMW every time. This car however was very inexpensive and I can say that it definitely draws more attention. Any time I was getting gas or just being around the car I got more dirty looks and sneers from people than any other car I've owner. The only car that was close was my 92 MR2.
The biggest downside to these cars if buying new is horrific resale value. I mean absolutely terrible in every way, no matter the model or equipment you will lose your shirt on these cars. i sell Hyundai's new and I use to think they had pretty bad resale but nothing like buying a Jag new. It's a car you buy if you plan on either keeping it for a long time and just have to have the styling of the jaguar. just know that if you buy it new you will lose out terribly.
However it can be a fantastic bargain if purchased used and you probably would be better off to buy a higher well maintained example than paying the premium for a low mileage car.
