Darick, Definitely check the actual air & ground speeds. Like Ed, I'm suspicious of those speeds.
My Coupe normally cruises at 90 to (maybe) 95 knots. I may see about 100 knots at WOT. I also fly loose formation with C-85 Coupes and my plane is maybe a tiny bit faster. Climb is a bit better than the C-85. However I would expect very little difference between the O-200, and C-85 with the O-200 crank & new (O-200) cylinders. Again, my Coupe has the O-200 engine.

I think I may buy it! Darick, Beautiful picture. Be sure to send it to webmaster at http://ercoupe.org so it can be included in the rotation of in-flight Coupe pictures on the home page. How did you accurately measure that "120 mph in no time in level flight"? Be aware that airspeed indicators, when they're getting inaccurate (and it happens a lot) often or usually show higher airspeeds than what you're really going. My old Coupe showed 115-118 in cruise all the time and I wondered why my trip time was so much longer than my careful flight plans said they should be - headwinds both ways on short trips? Doing really accurate calibration showed it was way off and I was really going 100.3 or so, true. The replacement airspeed indicator showed accurate airspeeds after the appropriate calculations for density altitude, etc., (checked again with really accurate calibration procedures). In other words, I'm suspicious of that airspeed report in a Coupe (as opposed to an Alon) even with an O-200. Measure twice, pay once - as carpenters say.
