SR50 WWW purchase advice

Hello, I have an offer for an SR 50 WWW (Minarelli engine) with 11,000 km and year of construction 2000. The scooter is in good condition and has 2 new tyres and a new Variomatik. The price is 800€ is fair? And will I still have a long time to enjoy the scooter? Have read that the old Aprilia scooter with Minarelli engine are very robust, can you confirm that? Thank you and a nice new year.
