Kelley's Blue Book value of a 1995 Del Sol with 130,000 miles and the model with the B16 in excellent shape is $3,485. Good is $3,085, and Fair is $2,600. Basically it comes down to what its worth to you, but $8k is too much for it.
That is why I said I wouldn't pay more than 4k... Motor obviously has some issues that are beginning, why pay a bunch of money for it.
