Spring season is alive and well, said Black Book’s Ricky Beggs in his weekly report, as harsh weather conditions are calming down. The three car segments that saw overall increases two weeks ago — the upper midsize cars, the entry midsize cars and the entry level cars — all saw price hikes again this past week. Compact cars also joined the ranks of car segments with price growth – jumping up $10 last week. Full-size cars also showed more stability, with only a $7 decline last week. Prestige luxury cars saw the biggest drop, falling by an average of $201.
