What weight baseline? I see reports from 1698 to 1874lb. This car's owner estimates 1300lb. That's 400-570lb difference. Did you notice all the speed holes in the seats, pedal and brake handle?
100 MPG was an aspirational goal. Has anyone achieved that other than Aerocivic?

1) According to Hucho, who ran VW's climatic wind tunnel for a decade, the Coupe has Cd 0.34, Af 1.61-meters-squared, for a CdA 0.5474 m-sq. The Speedster, with it's ragtop up,with it's side curtains has CdA 0.6046 m-sq )
2) The Speedster gives a 'virtual' Cd 0.4032, when the ragtop is lowered and side curtains removed compared to the Coupe, @ CdA 6.9873-sq-ft ( 0.6491-m-sq ).
3) The curb weight for Coupe = 1920-lb, Speedster = 1750.
4) The 550 RS was 1,300-lb 'dry', 1,510-lb with fuel, plus 370-lbs for two occupants
