Well...
I know mine is NOT the most beautiful in the world, but he is beautiful to me for so many reasons.
Alas, I cannot decide on ONE, but here are a few of my favorites and why... and in NO particular order.
1. Bob Brown's built, Jim Schultz' "Trailer Queen"
Heavily modified but all original in its appearance. One of the highest prices paid at the time for an X1/9 and worth it. Simply FLAWLESS!
2. Ulix's yellow car, now in Germany.
He races this car all the time Nurburgring and had a near fatal (for the car) accident many moons ago. Restored back to this level again and continues to race.
3. Brett Melacon's RHD
I can't find the "fall" photo of this car with the top off, its beautiful saddle-toned interior, flawless paint and surrounded by autumn leaves. He lives near the "Tail of the Dragon" roadway infamous for its turns and twisties going on for miles. I u/s he "exercises" his ride quite frequently.
4. Peter, in the great North East!
He constructed this show-stopping "rally look" ride a few years back that impressed the FLU gang so much it made it to the front page of their calendar.
Whoops, another shot... if only his beautiful daughter would get out of the way...
6. Chris Wright in the land down under...
Most any... probably EVERY Dallara bodied X1/9 is my favorite, this one is done exceptionally well (IMHO) and I just LOVE those wheels!
6. Wayne Wright's GM V6 Powered X1/9
I always said "He coulda had a V8..." and there is obviously room for it. Great engineering using a Caddy or Olds split Turbo-Hydro trans. I believe Mike Mittelstead owns this car now.
Oh... and here is a guy that not only planted a V8 in the back, but used a 429 Caddy and trans out of an El Dorado.
There was once a video of this car and it was CRAZY to watch! The front end was never upgrades and the car simply would not stop. Worse yet, it wouldn't turn either!
Alas, SOME of this "modification" was well engineered, but MOST of it wasn't. Note the reservoir mounted high on the right upper side of the Targa Bar.
