There is a CRX for sale on my way to work. The "For Sale" sign has no number and I go by the house at unreasonable hours to stop in. Sign says it's a 1990 with 140,000 miles. Are there easily identifyable characteristics to tell if it's an HF? It's a 5-spd with a sunroof and a rear wiper. Obvious bondo repairs around the rear wheel arches.
