First off, thanks to all who have responded so far, the information provided is really helpful, and I appreaciate the time spent to respond in such detail. To clarify my goals, I'm looking for a "b" in Carl's list, a good, drivable weekend car that I can incrementally improve, as time and money permits. I'm not a perfectionist, but place importance on the fundamentals: straight, solid body, and strong mechanicals (motor, tranny, suspension). With regards to budget, I'm open to laying out 3-6k for the initial purchase. The only other requirement is California specific, as I am interested only in those years of the Z that are smog exempt. Honestly, I'm not experienced with Z's to know if my expectations match the money I'm willing to commit to this, so let me know if what I have is a pipe dream or something that can be realistically achieved. Thanks all!
