Frank, thats not at all common. Thats the cheapest one I have ever seen in my life.
A good 94ish, in good condition, reasonable milage/service history and a fat list of mods will set you back approx 4-5Keuro, so approx 5-7.5k USD.
Alan:
There is that one dshamrock mentioned for 550euro, its a 90 with no NCT and may need some work, but could be worth it, however, I recommend you get a REV3 up for better brakes, suspension and handling.
There is a guy on here called reckless selling is 94 N/A, which is ideal for you mate:
cars.donedeal.ie/for-sale/cars/1252932
The ad is 1200eur but he is fitting a new clutch now and will then want 1500 but you could talk to him.
Try not to freak out too much, I was months and months looking before I found mine, ask Dave, I was going mad, but he is right. The more you spend, the more you get, but for your first one, you dont want a turbo so that eliminates all the turbo timers and all the other turbo related extras that usually add value. A reasonably stock N/A should be a bit cheaper than a modded turbo. Keep the faith, keep saving, keep looking and keep the cool.
