Faults:

Apart from normal wear (brakes, clutch, shocks etc.), the only major problem was a leaky fuel tank because of serious corrosion.

Rust is also a problem at the body, but it is manageable when you don't wait too long.

General Comments:

This was one of the best-selling cars in Europe in the late 70s and early 80s, because of its many virtues:

It wasn't expensive, neither in purchasing nor in maintenance (and it still isn't).

It is very roomy and comfortable.

With the top engine (110 hp), it really was a fast car.

It was available in many different versions from basic and simple to luxurious or sporty (in Germany even a version for hunters or forest wardens was available)

Although its overall appearance is hardly modern, it still has a rather timeless look (most people estimate the age of my car at 10 to 12 years, while in fact it is 28 years old!)

Faults:

The fuel filter got clogged at 13.000 kilometers (97+ fuel octane rating).

Gas tank gasket ripped at 14.000 kilometers.

Intermittent stalls not associated with clutch and driver failure.

It's a gas-guzzler and there's no doubt about it.

General Comments:

The steering is highly responsive and you can use only one-hand on 160 degree zig-zags.

The suspension is a bit troubling especially at the back, but it never lets the car down.

I got a lot of good comments and looks when I bought it even though it was third-hand!

The original jet black paint is magnificent and it feels that it actually is a limousine.

Mine is an Irmscher edition so everything is made to look sportier, with fiberglass and high-impact plastic as the side wings and both of the bumpers and also the nice Momo-Opel steering wheel.

It has a lot of features that set it alongside the luxury cars of Mercedes, etc.

The brakes have a bit of latency, but it never fails to make you feel safe.

The seat warmers and sun roof are proof that it is a luxury car then in the eighties.

It's not a racer nor a snail, but it never fails to out-speed other modern cars.

Faults:

The starter broke at 40.000 km.

Clutch went at around 30.000 km, and again at around 40.000 km.

Gearshift lever went from 4th to neutral when hitting any bump, from around 50.000 km.

General Comments:

A gas guzzler, wouldn't go more than 6 km per liter in the city, and perhaps 9 km per liter in the highway. 6 cylinder automatic consumption in a 4 cylinder manual car.

An excellent showcase of General Motors mid and late 70's styling that was not hampered by U.S. regulations.

Very comfortable car, except by the leatherette upholstery which got too hot in summer.

Great ride, felt like a really bigger American luxury sedan.

Best steering I've ever tried, enough power assistance, sensitive at speed, very easy to park.

Very nicely finished car.
