[MR2] auto mk1 vs 5 spd mpg

[ron ewing]

    Hi guys.  I'm thinking of trading a good 93 miata I have for a very clean 87 auto mk1.  With the overdrive, do you see much in the way of improved hwy mpg?  At 70, the engine is only turning about 3000, vs 4000 on a 5 spd.  Not the most exciting drive I know, but for hwy cruising (and maybe for my 
manual-challenged GF) maybe it would be OK.  Good reliablity with the auto boxes?  BTW, if anyone is interested in the Miata and has a good mk1 5 spd with cruise not too far from Cols, OH, drop me a note.  TIA, Ron.
