>>180% in taxes on a car
Yep, that's what socialism will do for ya! Will happen in the USA (or at least lefty California) before you know it.
In any case...you got a running 911 for $6000 (which is PEANUTS in Euros!) I see decent inner fenders and front pans but some rocker panel and rear panel rust...only the most pristine southwestern cars don't have that! I've seen much, much worse rusted cars than that saved...you got a great deal.
That will make a sweet RSR replica,..the steel flares, giant tail, and RSR front bumper are already done, you just need a better color and a backdated '73 RSR rear bumper! I'm picturing that car in Viper Green or Gulf Blue with a gold "Carrera" script on the side to match those classic retro racing wheels. Don't get discouraged...just learn how to weld a little and be creative. Think of it as sweat equity.
