No wrong answers here, just looking for opinions. The car in question is a 1994 Miata M Edition. Here's the "pro" and "con" AFAIK. First, the con. I live in Michigan, so the car is off the road 4 (normal year) to 6 (last year) months out of the year. I have a tin-top daily driver that has working AC. I don't drive the Miata if its super hot (partially because of the non-working AC) or if its going to rain. It's not a "cream puff" car. It is a solid looking car from 5-10 feet, but doesn't really have any current or potential "collector" value, as it's been resprayed and had a Hard Dog roll bar installed. It's also had the rocker rust repaired, which is why I don't drive it in the rain. It's clean on top, under, not so much. It gets driven 2-3 days/week to work, on weekends and to autocrosses and various other events. Pros: It's a relatively low mileage car (roughly 100K), has a pretty clean interior and, through a series of small projects, everything except the air is currently working. The wild card is it may be for sale in a year or two. My mechanic looked at it and said all components are there and appear to be functional, it likely just has a leak somewhere that would have to be tracked down and fixed and the system recharged. It doesn't require any coolant fluid conversation. His quick "guesstimate" was a few hundred for everything. DYI is beyond me on this job.
To fix, or not to fix, that is the question.
