While critics raved about the Calibra's looks and performance, they were less keen on the interior which, despite sporty looking seats and some nice detailing, used a dash lifted straight from the Vectra. The Vectra also donated most of its chassis, which led to some less than flattering road tests at the time. The critics were especially harsh about the gearchange, vague steering and low-speed ride quality, although praise was heaped on the car for overall refinement, keen prices, practicality and performance.

I was too broke for a proper fix so a friend welded a glob of metal to the worn end of the shoe and we ground it flat to make a bigger surface for the brake cylinder piston to hit, then soaked the brake shoe in gas and lit it to burn off the brake fluid! Insane when I think back on it, but probably not the dumbest thing I did in my teenage years, and those brakes lasted several more years!
1Opciono. Funkcioniše automatski iznad 5 km/h i ispod 85 km/h. Od 5 do 30 km/h, indikator usporenja da bi se umanjila brzina udara pri sudaru je 0.9 g. Od 30 do 85 km/h, sistem smanjuje brzinu za maksimalno 22 km/h. Nakon ove granice, vozač mora sam da koči kako bi dodatno smanjio brzinu. Raspon operativne brzine AEBPD-a zavisi od vrste otrkivene prepreke (pokretna meta: od 5 do 85 km/h; fiksna meta: od 5 do 80 km/h; pešak: od 5 do 60 km/h). Namena Opelovih sistema pomoći vozaču je podrška vozaču u okviru sistemskih ograničenja. Vozač ostaje odgovoran za zadatak vožnje.  Očekuje se da će biti dostupan od jeseni 2017.
As in the 1993 released cars' case, there were no notable differences between the 3 and the 5-door versions except a larger wheelbase and slight cargo volume increase. The choice of engines was kept the same with only a few upgrades having been made, leading to the introduction of new equipment levels such as the 1.4 i 16 V Strada and Onyx. As for the Diesel engines, the 1.7 Liter were kept...
We took the ferry from Newhaven to Dieppe and then headed down to Forges-les-Eaux, along winding D-roads through quiet villages and dense forests, scenes to be repeated over the following three days. What you notice immediately about the Calibra is how civilised it is. That V6 engine is a gem, not especially powerful by today’s standards but honestly quick and genuinely refined.
Power first came from 1.0 L 45 hp, 1.2 L 55 hp, 1.3 L 70 hp and 1.4 L 75 hp petrol engines. (The first engines were all equipped with carburetors; fuel injection came later, but never for the 1.0.) The engines were based on the well proven Family II design,[citation needed] except for the 1.0 L and early 1.2 L engines, which were based on the OHV unit from the Kadett C.
It had some crazy mechanical issues. At one point it stumbled and stalled because the carburetor had come loose from the intake manifold and I had to tighten it back down! Another time, my brother was driving it and the brakes failed. Somehow the end of the brake shoe that meets the brake cylinder piston had become worn on one side, causing the piston to slip off the end of the shoe when the brakes were applied, losing braking and squirting fluid all over.
