For private use, the Y31 was built from late 1987 through 1991, available as either Sedan or Hardtop versions. This generation was one of Nissan's most popular series, as the Japanese economy was very robust before the advent of the Japanese asset price bubble deflation in mid-1991. The styling of this generation was more rounded, and additional attention was given to luxury accommodations and optional features. The trim packages were similar to the previous generation, with some changes. The top level package for the hardtop was the V30 Turbo Brougham VIP, followed by the V30E Brougham VIP, V30 Brougham, V20 Twincam Turbo Brougham, RD28 Brougham, Classic SV (V20E or RD28 engine), Classic (V20E or RD28 engine), V20 Twincam Turbo Grandturismo SV, V20 Twincam Turbo Granturismo, ending with the V20E Granturismo. The sporty GranTurismo version has short bumpers with body kit, and powered by 2.0-liter VG20DET engine, which replaced the previous generation SGL, GL, while the Classic replaced the Urban designation.
