Only small minor problems.
Well this is a poor man's Porsche, it handles like it's on rails, and the speed of the car is deadly, it will thrash any crappy Ford Cossie (they are crap cars) and keep up with Porsche Boxsters. I think that says it all!!!... bye bye Cossies.
I have to agree about the crappy Fords, its not just the cars, but the type of driver they attract, one step away from a BMW driver.
However, granted the Calibra Turbo is a very quick motor, but it's a bit of an overstatement to say it "thrashes" Cossie's. The Calibra shuffles off the mark to 60mph in 6.4 seconds where as the Cosworth can do the same sprint in 5.7 - its hardly a "thrashing".. but your spot on about the Boxster, well unless it's the 3.2 litre!
Still nice car, if only Vauxhall could have applied better build quality and styling to their other models then perhaps the often overlooked Calibra wouldn't have taken such a hammering on the used market!
BTW... what made you swap a Skyline for a Calibra?
It doesn't say anything about the Calibra in this review (if you can call it a review) being modified. If not then it's not gonna thrash Cossies or keep up with Boxsters. And the handling? You must be joking!
