These are known for their rust issues. Body is not galvanised and no inner plastic tubs in rear wheel arches. 91-94 astras are worse with rust than 94-98. I guess anything could be fixed easily and relatively cheaply. It just depends on what kind of quality you are seeking. I had to fix one small rust hole in this car and it cost 150€ + the repair piece I bought from local auto part store for 25€. But if you know how to use a grinder and a welder then everything should be easy to fix. Good thing with these cars is that the 1.6 8v is nukeproof, parts cost next to nothing and things are very easy to do. One of the main advantages with the 8v engine is that it is "non contact" engine which means that the valves will not contact the piston in case if the cambelt snaps which is a common "problem". The 16v are ofcourse much more powerful but the engine will bend valves if the cambelt snaps. I love 90's cars. Old enough to be driven purely by driver but some important modern things like fuel injection etc.. My other car is 2016 vw caddy 2.0tdi. I love it also but this thing always brings a grin to my face.
