There are loads of info threads on here as to what is good and what is better. Also, lots of peeps who think theirs is better than anyone elses....

Ultimately, the Elite spec is the one with the most toys, the MV6 is arguably the best handling, with assorted CD/CDX etc others with various toys and bells and whistles.... You choose your spec dependant on what you are looking for.
Enginewise, the 2.0 are the most flat, with the 3.0/3.2 giving the better power/torque. The 2.5/2.6 can argue power versus torque/economy, with the 2.2 a close second.
The 2.5 TD is an old detuned BMW engine and relatively flat. The 2.2 is a tad better.
The cars weigh in at close to two tonne, irrespectuive of saloon or estate, so unless you have a tame nuclear reactor to fit, they will not give the best economy known to man....
At the end of the day, get a car with the trim you want and within the budget you want to pay. Let the engine take care of itself....
Theres always LPG if you want to stay petrol, by the way!!
