Los Angeles-based vintage Porsche specialist Workshop 5001 may be new to the street, but their German mastery dates back long enough to warrant their skills in the garage. Their No1. car is a narrow-bodied '73 911 powered by a 3.4-litre flat six putting out over 300bhp. It's an impressive full restoration reinvigorating how a 911 should be driven. Check out the near-perfect build below.
