The volume Cadillacs were heavily facelifted for 1958 in a manner typical of GM that year. Perhaps the most garish Caddys yet, they were laden with chrome and far less stylish than previous postwar models. Sales were poor, though a nationwide recession was probably more to blame than the baroque styling, which was, after all, in vogue. At 121,778 units, model year production was lower than at any time since 1954. Symbolizing the fall in fortunes was a V-8 slightly detuned in a faint nod toward fuel economy, limited to a single 310-bhp version for all models.
