Well, these are two pretty similar cars we have here! It's only details that could potentially make the difference. Considering they both belong to the sports car segment and utilize the same 2-door cabriolet body style and the rear wheel drive system, it all comes up to the specific petrol engine choice they offer. Both the engines are Opel-engineered . The first one has a 4-cylinder, 16-valves 147hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 264hp one.

Unfortunatelly, neither of the two vehicles was submitted to the European New Car Assessment Programme (Euro NCAP) testing. This makes it virtually impossible for me to pick one over the other and I'm generally against buying such cars as the safety should really always come first. That aside, let's consider some other aspects which affect safety. Both vehicles belong to the sports car segment, which is generally classifying them somewhere in the middle safety-wise, but that fact doesn't break the tie between the two cars. On the other hand, taking kerb weight as an important factor into account, Opel GT offers a self-explainatory difference of 50% more metal.

Manufacturers have been building their reliability reputation for decades now and, generally speaking, it appears that Opel sits somewhere in the middle fault-wise, when all the models are taken into account. That's the official data, while our visitors describe reliability of Opel with an average rating of 4.2 out of 5. Unfortunatelly, I don't have enough insight that would allow me to comment in more details on the specific models level. Above it all, drivers of cars with the same engine as Speedster rank it on average as 4.2, while the one under the competitor's bonnet gets 3.0 out of 5.

Opel GT is a bit more agile, reaching 100km/h in 0.2 seconds less than its competitor. In addition to that it accelerates all the way to 229 kilometers per hour, 12km/h more than the other car. When it comes to fuel economy the winner has to be Speedster, averaging around 8.5 liters of fuel per 100 kilometers (33 mpg), in combined cycle. We can't ignore that 8% difference compared to Opel GT.

Speedster appears just a bit more reliable, although the difference is truly marginal. The most important thing when deciding between any two vehicles should always be safety, both passive and active. In my opinion, everything taken into account, Opel GT beats the other contender by far, making it the best choice without even considering other things. It all continues in the same direction, with Opel GT outracing its opponent in any situation possible, making it better choice for boy racers. It does come at a cost though, and that's the fuel consumption... No mistake, whatever you decide here, but I'd still go for the Opel GT. Anyway, that's the most objective conclusion I could've came up with and it's based solely on the information found on this website. Aspects such as design, practicality, brand value and driving experience are there for you to measure them out.
