From 1957 to 1961, Rometsch produced the Lawrence model, drawn by Bert Lawrence. Approximately 200 vehicles were produced at Rometsch. Friedrich Rometsch, like his colleague Beeskow, worked for Erdmann & Rossi before founding his company in 1924, which initially profited from the fact that many car buyers only purchased a motorized chassis from a vehicle manufacturer, which they had a coachbuilder or wagon maker (Stellmacher) fit with a body to their specifications. This habit ended in the late 1930s, when it became common to buy complete cars from automobile factories. In the early 1950s, Rometsch built cabs. The first was built by designer Johannes Beeskow from a scrap VW Beetle.The two-door Lawrence model was a Rometsch in-house developed body, also built on purchased VW Beetles. Named after its designer, it was produced as a coupe and convertible and won several awards at the Geneva Motor Show. About 17 of these vehicles were built annually. Just 115 of these coupes were built.

Carl F. W. Borgward commissioned Rometsch in 1951 to build a sports car on the chassis of the Goliath GP 700, similar to the two prototypes built by coachbuilder Johannes Rudy of Delmenhorst. The car resembled the Porsche 356, but appeared more elongated thanks to a longer wheelbase – 230 cm instead of the Porsche’s 210 cm – and a slightly curved side line with a rear fender landing. Rometsch exhibited the coupé as early as the IAA in Berlin from September 6 to 16, 1951, and it was praised in the press as a “treat for car enthusiasts,” among other things. Buyer interest in the car, which was sold exclusively through Goliath dealers and, at DM 9,700, cost only DM 500 less than the Porsche, was low, however. But the relatively high price was probably not the only reason for this reluctance. It is also possible that the 36 hp two-stroke engine did not seem very attractive compared to the Porsche four-stroke with 40 hp. Only 25 vehicles instead of the planned 50 were built by 1953.

Sales of VW-based cars later stagnated, not least due to competition from the VW Karmann-Ghia Type 14, which was cheaper by DM 1500 and was also built on the VW Beetle chassis. Volkswagen general manager Heinrich Nordhoff stopped deliveries and forbade dealers to deliver chassis or even entire VW Beetles to Rometsch, whereupon Rometsch could only buy entire vehicles through straw men, which had to be dismantled afterwards.
