Not sure about the vxr itself but that astra h (???) is a pile of shit car,I've been trying to help a couple of folk in work with their ones and they've both needed ecu's at a cost of a grand upwards which is poor IMO,one was an 08 reg!!!

Renault.guy in the unit next to my old one had one and it went through 2 window mechs,switches etc but no engine issues and was a quick car with superb handling and IMO looked pretty in blue.
That said it wasn't that old at the time,perhaps 3 years and mega low miles.
He also said it was dismal on petrol and heavy on tyres.
FRS,more a weekend car I would say although they are reliable,I'd just be afraid of leaving it anywhere personally,people trying to steal it etc.
For me,I'd go focus St,and this is a car I'm seriously considering myself in the future.
Strong Volvo lump,great chassis,infinitely tuneable/styleable but still a pretty looking car out of the factory and popular enough to blend in nicely in a carpark etc and not attract your local TWOCers!!!
Only issue is fuel consumption and if that's not an issue then I'll see all of the above and raise it to a nice impreza,the rest don't even get a look in compared to one,does all of the above but more reliable,better handling,more tuneable and IMO better looking.
Don't know much about the big audi mentioned but they don't make shit cars so that's worth considering too.

Tough descisions young man!!!
