Verdict
The clearest difference is rating: BJ at 2.8 against Car's 1.6. BJ also leads on review sentiment (50% vs 9%) and update cadence (every 5 weeks vs every 7 months). Car's advantage is ratings volume (129 vs 9). On price, ads, in-app purchases and monetization model there is nothing between them.
