Yeah, I guess if you got that kind of money for a hobby driver, any of these could be your thing. My problem is I remember when I bought a new 914 in 1974 for $6,700 cash. For another couple of grand, I could have had a brand new leftover ‘73 911 in silver with salmon leather interior. With sunroof. Stupid choices when you’re young.
Not many sports cars in the under $35k range. The new Fiat 124 Spider approximates the old 914/911 experience, maintenance-wise. Mazda Miata might be a saner choice. Subie BRZ, Toyota 86, even a Nissan 370Z for a little more money.
Fortunately, there are many hot hatches, coupes and small sedans that are relatively affordable with good handling and sub-6 second 0-60 times.
