Maybe I don't make book numbers, but I'm sure faster than brand neighbor's brand X, and that's all that matters :)

It all depends on whether the airplane is stock, has modifications, what modifications, and how many. 

Not really. Many people do speed mods just to get it to be closer to book value.

100% true.  Speed mods on J were not really a thing.  It was all marketing.  The AS gauges were modded to make owners feel their planes were "worth it".  Those wacky 70's and 80's.

I bought my Mooney because:

  • I was finishing my license and looking
  • It was at my airport
  • It was the FBO owner's personal plane
  • Therefore it was in good shape
  • He was willing to sell it half at a time
  • Each half was about the price of a worn 172

I had 62 hours in my logbook by the time we filled in the pink slip, did the required 15 hours dual including 5 hours actual & simulated IMC,  and haven't looked back. It's been 1000 amazing hours since then!

Also, it's fast and efficient. As an engineer, I appreciate both! I can make the same trip as a 172, in ~30% less time and 10-15% less fuel. Oh, and i can carry more people and stuff while doing it.  :D

Why did I purchase a Mooney?

At my airport.

Told by Lynn (AGL)at the time it may be the best kept F on the planet. 
price was reasonable.

Owner had open checkbook policy.

Served all my mission parameters.

But mostly I just loved it. 
And fwiw it was a 148kt tas aircraft  

But alas all things come to an end.

Now a V35B driver.

:rolleyes:

So, in light of this poll and some of the responses, I decided to revisit what the "book" speeds are for my Mooney.  I looked them up in the AFM that is specific to my airplane.  So, at 5000 feet with RPM's at 2500 and MP at 24 inches, the "Book" True airspeed is supposed to be 180 mph or 156 knots.  Seems to me that is a little high for a C model.  So I went out and did the TAS check using the cardinal headings and GPS.  At 5000 feet with the RPM and MP set the same, I got 143 knots TAS.  10 knots slower than "Book".  So either I have a dirt slow C model, or I have lost a lot of speed in 61 years the plane has been flying or they had absolutely perfect conditions, with a perfect airplane, and a perfect pilot when they got their "book" numbers or a combination of all of the above.  And I was roughly the same weight as shown on the chart in the AFM.

I would really like to see any C model that cruises at 156 Knots true.  That is getting into J model territory I think.  No question here, just commenting on my airplane.

I think your Book was written by Marketing!

Below is the page from the Owners Manual for my 1970 C, at those setting it shows 164 / 167 mph depending on weight. If I remember, your C is 1965 or earlier, so in 5-8 years, the plane lost 15 mph!
