I purchased a 2019 Mahindra Scorpio S10 4x4 from WeBuyCars Silverlakes Pta on May 21st. Just 17 days later, the head gasket blew. WeBuyCars paid R30,800 for repairs at Mahindra Nelspruit. However, Mahindra discovered extensive damage requiring engine replacement, quoting R120,358.24 to R173,683.58. Tampering was detected, including the removal of the thermostat. I've submitted the report and quotes to WeBuyCars, awaiting their response. I need this vehicle for work and am disappointed in the experience. I never expected buying from WeBuyCars would cause such issues. I hope they resolve this promptly and fairly.
