car soft, yet firm, driving characteristics and excellent stability for such a big car. The engine range, however non-economical, was also very good, and few problems with the extremely reliable engines. The six-cylinder engines were all overhead camshaft. Many parts on the engine, such as the water pump and drive train were the same parts as used on the four-cylinder version. This meant that this was an engine not only tested for many years in the Commodore, Admiral and Diplomat range, but also very reliable. Although the first generation of 3.0E engines in the Monza A1 had overheating problems when standing still, this could easily be fixed by fitting an oil-cooler. Opel introduced the "C" package. The "C" cars were fitted with extra instruments (oil pressure, voltmeter etc.) and the interior was either red, dark blue, green, or brown. The A1 also came with a sports package or "S" package. The cars all where marked as "S" models on the front wings, and came with 15-inch Ronal alloy wheels and a 45% limited slip differential Four well-sized adults had plenty of space. Even the boot was large, and the rear seats flipped down to make even more space. The A1 was not a great hit at the customers even though it was relatively cheap. With the 3.0-litre engine, the Monza was at that time the fastest car Opel had ever built. Being capable of speeds as high as 215 km/h, and the 0–100 km/h mark went in just 8.2 seconds. Monza A2 (1982–1986) In 1982, the Monza, Rekord and Senator all got a face-lift and were named the A2 (E2 for the Rekord). The A2 looked similar to the A1 overall but with some small changes to the front end. The headlights noticeably increased in size, and the front was more streamlined than the A1. The car was much more slippery, with drag resistance down by around ten percent (from 0.40 to 0.35 ). Also the chrome parts like bumpers etc. were changed to a matt black finish, or with plastic parts. The bumpers were now made of plastic and gave the Monza the look of a sports car in appearance, and actually did look similar to the Opel Manta, despite the ample size difference. The rear lights were the same and the orange front indicators were now clear glass, giving a much more modern look to the car. Overall
