So, being in Spain, I want to buy a car. That’s what you do right?

Now this is where you, the opponaut, come in. I need to find a car, but I don’t really know what I want. I know that it has to be older than '91. Preferably not older than '80 and definitely a Euro only model. I have a few idea's but I don't know really anything about the Euro market so, please, point me in some right (or wrong) directions!
