Not at all biased, but have a look at the Saab 9-5. Even the low pressure turbo 2.0 (both the 1.8 and 2.0 badges are 2ltr) shift very nicely, or go the whole hog and get a full pressure (high output) turbo 2.3 (Captial T on later models (lower case 't' means LPT). The HOT version goes like hell on a stick.... ask me how I know.
1.9Tid is the same engine found in the Astra, Vectra, Alfa, Fiat etc. I've been told the 2.2 DIesel is a pig although I have no experience.
Very nice car to drive.... SWMBO hated driving the Omega as it was too big, but loves to drive the 9-5, even though it isn't exactly small.
Con's;
The dash is dated... very dated.
Aero Models (like mine) suspension is a little harsh on bad road surfaces, other models are spot on... the Aero corners like a small hatch though.
The steering is, for my taste, a litte over assisted.
Regualr oil servicing is a must. Saab enthusiasts recommend every 6k on petrol engines. I do mine every 3k. VX Fully Synthetic is perfect for the job.
For some reason, Insurance is expensive.
Pro's;
Great transmissions, either manual or auto - much better than the Omega manual which is terrible, and the 5 speed Asin Warner Auto box is just a joy.
All Petrol models are very easily and cheaply tuned (if that's your thing).... not only increase performance but also MPG.
The 1.9Tid is easily tuned as well, just like the Vauxhall equiv.
Boot is cavernous on the saloon, similar in size to that of the Omega - The estate is smaller than the Omega estate, but still very practical.
Seats (in leather (not tried the cloth)) are by far the best seats I've had the pleasure to sit in, including the likes of RR/Bently et al.
The best bit: Dirt cheap to buy. I consider my purchase as 'expensive'. £1995 for a very well looked after LPG converted '04 plae Aero in top spec. Every conceivable extra included.
A drive to Gatwick airport and back (from Bristol) stood me in at around £26. There aren't many 250BHP cars weighing 1600Kg that could do that!
