Ultimate boy-toy automaker Ferrari is apparently riding into its first ever city showroom, just one Park Avenue block away from competitor Mercedes-Benz.

The car company has chosen a luxe corner spot at 410 Park Ave., on the southwest corner of 55th Street, where it intends to display - but not sell - Ferraris and Maseratis.

Mercedes holds down a corner  one block north, at 430 Park Ave.

According to the Slatin Report, the 4,300-square-foot space was vacant for three years while the Cushman & Wakefield  duo of Gene Spiegelman and Michael O'Neill worked for the Eastgate Holdings ownership, carefully vetting all tire-kickers to find a creditworthy tenant.

At one point, sources told The Post, there were 26 offers, including one from BMW, which was seeking a showplace for its Rolls-Royce Phantom. That company may now be talking to Douglas Durst about  space at 57th Street and 12th Avenue.

Eric Lassoff, of James S. Meiskin's  Plymouth Partners, represented the Italian car company. Neither the brokers nor the owner could be reached for comment.

The asking rent was $150 a foot for the space.
