The fiberglass body is thick and well engineered, I spoke with Rafael in Mexico this morning he told me they widened this body to accept the Mendeloa chassis with the 17" Airkewlwed wheel$. I had to look at the back to see it was 2" wider it's nicely done and the only one wide stock body that exsists. Engine specs are unknown so I pulled a valve cover and the ports are oval shaped and the valves are huge. I asked Arden to let me know where the engine was purchased from so I can back track for info..... Jaguar Vapor Grey Metallic is the color choice. The speedster will retain the hoop roll bar and hard tonneau so it will be without a top to replicate an Emory. .................Recently someone was asking about a scissor top frame assembly: I am going to sell the top frame assembly, black Stayfast top and side curtains . This to when folded down rests on the rear body as does the Intermeccanica tops.
