i like each generation, hell each year! they all had good and bad points.
as for fourth gens... the base models could be very plain looking (same with each generation tho) however for me the 98+ Trans Am is the best looking one (hell even the 93-97's do it for me esp with the Ram Air 1 hood
), inside and out, thats why i bought one! the 96+ SS is a VERY close second tho
