Gerald,
Those '98 rims could get you $2,000 (possible more), if in good shape. Many people desire forged old-style 5-stars, to keep the original look and increase strength over 96-97 cast wheels. Therefore, $2,000 + $400 cash = a new set of 17' Purner's. Of course, I would wait till you need new tires, and spend the extra $100 for the 18's ($2,500). For new wheels, you can't beat Purner's price/quality/strength. It's also the most used rim/wheel at Viperdays, so it must be quality.
** Tip: If you go this route, I suggest the EBC greens. The one drawback to these rims is there bare aluminum (no clearcoat), and a beeeiiiaatch to clean. This is the reason I am looking into chrome plating my set.
