Here is your challenge.
You like some go, ALL front wheel drive cars with 'go' have stiff chassis's, its the only way the torque can be put on the road (the rules of physics are difficult to beat) be it Audi, Gm, Ford the lot.
So your either looking at AWD or RWD or having to compromise on a stiffer setup in FWD format.
Thinking similar sizes, the A4 you will hate, the handling is naff and there dead small inside, the Passat is the same car. The Mondeo is a good car but, they dont age well, the Insignia is an aquired taste, good all round and nicely screwed together but the looks for some are questionable (although there are MUCH worse cars out there!). French stuff as we know is hit and miss.
The Chrysler you will wrap round a tree within a month, they really dont do corners and are akin to a whale with an outboard motor.

Then you get into your favourites such as Merc and BMW.
Bloody hell Mr Fuse18, I think you've known me too long

That non-back-breaking suspension v FWD has to have a compromise found somewhere, as RWD choices are a bit desperate. I guess thats why I have a pair of Omegas

On Mr Clarksons understeer in the Vec C, if you drive and steer like they did in that clip, you could make anything understeer, the Vec C is actualy not nearly as bad a chassis as many make out, if they had done the sama in an Alfa (one of the best FWD setups out there) the result would have been the same (they applied fast excessive steering input to unstick the front wheel before straightening the steering up)
Nobody takes notice of TG (I hope), we know its for effect and entertainment. However, I'd still have to say, having driven a reasonable selection of Vectra-Cs (they were what our hire company used to supply my grade from days out), from small petrols, to 3.2 GSi's (not from Enterprise, they're not that mad

), and diesels, that chassis is abysmal. I found the Vectra-B a much better handling car, though cramped. But for outright hooliganism, the big petrol Vectra-Cs are great fun. Until your spine snaps.
