Bit of a Miata update/rants and raves:
Since the purchase, I have put almost 3000 miles on the car already. I like it a lot. Basically, all I have to compare it to is an 83 Chrysler LeBaron, a couple of Preludes, and a Lexus SC300, so I'll do my best.
The handling is very snappy, and it turns in hard. I can get the back end to break loose, and the snap oversteer is very predictable. I can tell the car is light just by how it drives.
I have been getting decent fuel mileage. Averaging 28mpg which is about 3 more on average better than the Prelude. I have noticed that to get better mileage I need to shift around 4,000RPM as opposed to 3,000 in the Prelude.
The interior space is a bit of an issue, but I've gotten used to it. The main issue is head room, but thats not going to be an issue seeing as how warm weather is on the way, and I have been going top down a lot already.
The transmission is another area of interest. 6-speed: the gears are very short, but overall mostly as long as the 5 speed from the Prelude IE at 80 in 5th in the Prelude I was just under 4,000, while at 80 in the Miata in 6th I am just under 4,000. This is more noticeable seeing as how the Miata spins 400 less PRM on the high end. 1st gear is like nothing, I had it sliding today on dry road, and before I knew it, I was bouncing off the rev-limiter (around 7,000 rpm)
The engine is pretty brilliant, but its no H22

It has variable valve timing, but not lift. It seems to come alive around 4,000, and by the time redline comes around at 7,000 it seems to run out of breath even though Mazda claims that max power (142hp) is made at 7,000rpm. It makes some cool noises at low revs, and I find that I can make myself smile even if I'm not hitting redline as opposed to riding the high lift cam from the H22.
So far, the only stuff I've done are the K&N drop in, the antenna situation, and the visor removal caps. Other than that, I have been vaguely shopping for a hardtop. I realized that they are pretty expensive and very rare, so hopefully by next winter I will have one. I checked the oil today, and it burned nothing. I really like this Miata, and even though I'll always have special Prelude memories, I am glad that I bought the car.
