Hey i agree little work to garage can mean alot to someone else and to be honest there are two reasons why garages sell cars one to make money and the other is to get rid of cars that dont,If its going cheap there must be some minor problems with it but to honest with a car that age it could be anything the only way is to go and drive it and ask the same question as above,look out for the exspensive parts on car and make sure they are in good working order like power steering pump,engine in general,brake servo,brake pipes,brakes,check all gauges especially oil as this will indicate if any problems with engine as in low oil pressure can mean oil pump on way out or excesive wear on engine,when engine cold oil pressure should be high 5bar because oil temp low but expect to go down to 3bar when warmed up
Hope this helps
