Oldtimer wanted for everyday operation

New idea, new project – the classic car for everyday use! Implementation: beginning of 2017 Budget: 10,000 € Hold time: min. 1 year (if it works, even longer) A vehicle with year of construction 1966-1986, which is to be used in everyday operation. Brand and model do not matter, whereby I want to explicitly exclude the luxury limousines and convertibles this time. So construction type Limo, Kombi or Coupé. Running performance 15tkm/year, all-year operation. Specifications: 1. Spare parts should be well available. 2. 12V-Ele ktrik 3. Seat belts 4. Seats with head restraints or the possibility of retrofitting them 5. A rudimentary useful value in terms of load volume (i.e. purchasing should be possible) 6. On the BAB a speed of 120-130 km/h should be possible at least permanently. 7. H-mark 8. Ideally an increase in value, but at least no loss in value 9. When buying TÜV new and acceptable basis (i.e. at least condition 3) 10. Disc brakes on the front axle would be nice. 11. Semi-functional H iitzung 12. Maintenance costs max. like my 13th consumption up to max. 15l/100km …and stop things I don’t think about now And no, I don’t want a golf, cadet or escort!!! Basically, I already have one or the other vehicle in focus, but would be interested in what you are thinking about. Or is there anyone who already succeeds? Someone who uses an old-timer as an everyday vehicle? What experiences have you gained with it? Greet Frank P.S. when I am there I would also report in detail on this and my experiences.
