It amazing how threads go downhill so quickly when people defend the car they love/drive.
I love my car (Vauxhall Vectra B GSI) and would defend it till the cows come home but I'd be realistic if somebody asked me is it quick or would this other car outperform it.
And IMO, 200bhp in a "normal" road going car (i.e. my car which has ~200bhp as standard and is a 4 door family saloon) makes for a comfortable drive with that bit of power that comes in handy, not for a rip-your-face-off scare-athon. Note the word normal.
And as for Astra GTE's etc, if the particular models your talking about came with the C20LET engine, its game over for most cars, even by modern standards. A simple remap sees these engines close to 300bhp without any other work whatsoever; this is why so many vauxhall owners try to get these engines and put them into there own cars as they are literally bullet-proof and can be made to develope fairly large amounts of power without too much work/bother.
The Calibra turbo (which is 4wd btw and has the C20LET, and the F28 6 speed gearbox) in standard trim would do 0-60 in around 5.5 seconds, and thats with only 200bhp (actually 204 if I remember correctly), a remap later could see this drop well below 5 seconds. Vauxhall may of not produced many quick cars, but the ones they did bother to make are fairly quick.
If anybody ever gets the chance to drive a Nova with one of these engines, I'd seriously recommend it: These car/engine set ups have been known to give supercars a run for there money (300+ bhp in a car that weighs about 600 - 700kg, a receipe for fun/disaster to say the least)
As you can probably tell from my examples, Vauxhall is my manufacturer of interest; please don't hate me for this, somebody has to do it, lol.
