Hi,
I've got the 2.5TD BMW, and for me it's fine - but if you're after power it's the wrong car.
I do around 80-100 miles a day on motorway and get around 40mpg (according to the computer). If I'm really delicate then I can push that up to 42, but if I'm heavy footed, drive over 70mph (I mean - who would do such a thing...) then I'm down around 32-35.
Economy drops off quickly as you push it. Starting up first thing and mine sounds a bit rough (but that's diesels I guess), once warm it's pretty smooth as diesels go.
There seems reasonable torque in the engine, but nothing to write home about - I tow a bit and it seems fine with that, but again the economy is wasted as the car tends to spend more time 'on-boost' above 2.5k as you haul along. (My trailer is a small box trailer weighing in at less than 700kg).
Press the 'Sport' button (I think all the 2.5TD's were autos - someone else will probably know) and it's rapid enough, but don't expect to be powersliding or lighting the wheels up in just about anything except wet conditions. Hell - it weighs nearly 2 tonne - why anyone would want to try and drive it near the handling limits is beyond me, it's a big car, and feels like it. It's no nimble GTi - but a great way to eat up the motorway miles in comfort.
Haven't taxed mine yet (due next month) but reading about the CO2 output then it's going to be fairly hefty bill - even more so if we get more 'green' taxes in the future...
I'm told the waterpump is a particularly weak spot on the engine, but I've not had any big problems yet ('98 saloon). Only thing I'm worried with at the moment is wishbones (every Omega suffers) and possibly a Thermostat (but I'm hoping it's a temp. sensor). I've replaced the radiator on mine and that was fairly pricey as they go.
Oil Changes!! Every 5000 miles on the 2.5TD is recommended by VX, and by most other people I've spoken to.
Well, there's my 2p...
