Verdict
The clearest difference is rating: Zelter at 5.0 against CarTrust's 4.0. Zelter also leads on review sentiment (100% vs 67%) and update cadence (weekly vs every 2 months). CarTrust's advantage is ratings volume (7 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.
