I'll also agree with Harmut.  Do you really need all those steam gauges in your coupe?  Plus, I always love to tell the story of how I learned how to fly in my Ercoupe.  And that was after I had my commercial & instrument rating.

My thinking : As a VFR Pilot, when do I need a artificial horizon most, if at all? I turns. Do I do turns in a fast level cruise attitude?
If you need an artificial horizon to be able to fly level in cruise in VFR conditions, you should rethink your general abilities to fly. If you think that gyro is good when flying in MVFR conditions, and you need a gyro to do so - hand your wife you last will already.
 
However, if you think you need that extra drag of a ventury and the extra weight of a HG just to have the right fun in a Coupe, I would say have the ventury attached level with the window sill and have in mind that on climb out the HG might not be that responsive.
 
I would not put a vacuum driven DG or HG in my plane. You either pay with additional drag and non-reliability in slower flight or you pay to rebuilt an air pump every so often.
I rather spend that money on an electronic solution.
 
Every handheld GPS is a better substitute for a DG and HG are already replaced by pricey glass cockpits, but there are also some cheaper solutions out there. (http://www.sportflyingshop.com/Instr/Stratomaster/SmartSingles/AttitudeIndicators/attitudeindicators.html)
 
Drilling holes into the expensive skin of your coupe to install outdated technology without being required by FAA law to do so is something I would not do.
 
Now that will hopefully stir up some discussion here .
