Can somebody tell me the difference between the Legend Coupe and the Legend Coupe LS, please?

man this forum is slow as hell i asked about the wiring diagram for a radio and never got a response
but as for your question all the legends are nice!

According to the 1994 Acura brochure, the LS Coupe adds, as additional standard equipment:

215/55 R16 V rated tires (instead of 205/60 R15 V rated tires for the L coupe); Traction Control System; Passenger 4-way power seat; Automatic climate control; Premium music system; and Heated front seats.
