True, and cars often go for a lot less than what a good example would be worth in a private sale.
If it's also involving handling and braking, the S13 gets even better. I would also recommend an 86, but it's hard to get more power out of them, since you only have 1.6 liters to work with. Of course, with a good turbocharging, or a swap to a 20V.

They would all fit in an 86
