Jaguar XJ Series II

(Picture by Martin van Duijn)
This is a Jaguar XJ6 Series II, which has been built from 1973 to 1979. The car in this picture does not look to rusty, just the dirt coming with time has covered the paint. It has been abandoned in the garden of a house nobody lives in anymore. The car seems to be a bit customized with tinted windows, extra chrome around the wheels and white sidewall tires. So somebody seemed to have liked it before it was left to rot.
It once was a large luxurious limousine with 3.4 or 4.2 litre engines. Nearly 130000 Jaguar XJ Series II were sold, including the coupe-version. The XJ6 cost around 65000$ at that time.
Nowadays, it is not especially rare or expensive, although very good examples can cost more than 25000$.
In better condition, the car looked like that:
