Jim,
I'm retired and lucky enought to be living in Mexico where everything is very affordable. Having my own Spyder mold, it cost me under$10,000 dollars to complete one with dual webers, fuchs wheels, vdo gauges, paint, wiring etc. If I was living in the States, this would never happen.
Made a mold of my 1985 Carrera Targa and just finished my first replica. Mounted it on a 1987 VW fuel injected engine. Bought back a black grill, logos, side view mirrors,fuchs wheels, instruments, seats etc from Florida.......only way to tell the difference is when I open the hood. This one took me a year to build too.
Yes, your right Jim, 3 sounds like a lot of Spyders ( all have different window treatment) but it's the passion to build them myself that keep a retired guy going. Check out my webpage if you want to see some of the cars i've build..... www.dominickonline.com Peace, Dominick
