I had a Mk2 1300 2 door and I recon it was one of the most fun cars I have ever owned. Sure the little motor didn't have to torque to spin the wheels on oil but it was like driving a go-kart, I only ever used the brakes at the end of the driveway.
The Mk1 2-doors are nice (my brother has 2) and would be my pick but unfortunately they are everyone elses and consequently the prices are high for a good one.
There is heaps of info around for modifications on these so you can easily get them to perform well enough. There was a Mk1 with a SR20 turbo at the drags giving yellow rolla a good run for his money, doing 12.0 or something.
You could do a lot worse than an eski for a first car.
