Great post, Foolish. Up here in Canada the miata/mx-5 is still a bit of a hard car to come by used. Even if used with 150,000kms the asking price is around $5,000. I want to get a two-seater, coupe/convertible to cruise around in the summer pretty much, with light autocross. Also I was planning to boost it in the future, not heavy boost but around 170whp with 'pep'. I was thinking it would be perfect on a miata, especially with its light chassis.
If I got an old rx7 and rebuild the engine, it would last me a long while right? I heard it was pretty to take in and out the rotary and rebuild it. Well, more simple than piston engines anyways. I have my own tools about 2000$ worth and up, and access to my hoist at work (I'm a second year auto apprentice) so I'm thinking it wouldn't be bad to learn on...
If they say the miata is pretty much bullet proof it would be alot easier on the mileage... Perhaps I should just go test drive both and see which one I'll fall in love with!
