Help required on a pre owned Contessa

hey guys.
i ‘ve come across a pre owned contessa that is up for sale
it is a 1999 Diesel
owner is asking a negotiable price of around 90k
what are the things i should look for interior / exterior , engine
i just need the car for short city runs no long drives as such until i m completely sure about the car.
i m 6"2′ so comfort is my main concern and second comes maintainence.
How is the spares availability of this vehicle?
