Looking at pulling the trigger on the 2018 Honday minivan. Houston dealerships offer the standard 5 years 60k miles powertrain warranty. San Marcos Dealership has the lifetime powertrain warranty; with how fast these things are flying off the lot, I know I'm not going to get much off MRSP from any dealership. So would it be worth my time to make the drive to San Marcos for the lifetime warranty? Their website claims you don't have to take it to their dealership for the maintenance to keep the warranty kosher. Any experience with this dealership?
