Evaluation: Showing 19,824 believable miles, and they weren’t accumulated in quarter-mile increments. The paint shows mild age but no major flaws, and the plastic body pieces are all in remarkably good shape. The interior is similarly clean. Only the faded plastic mirrors betray this Syclone’s true age.
Bottom Line: Thanks to their famous Ferrari 348-beating turbocharged performance, the GMC Syclone and its Typhoon cousin have been on collectors’ radar for several years, and their values shot up before the wider surge in the vintage trucks and SUV market that we are in the middle of right now. Syclone/Typhoon prices plateaued in 2016 and have steadied since. The price on this one is quite strong (lower-mile examples have sold for less) but it isn’t outrageous.
