I'm saying I got a quote with Costco Travel for 184 GBP and a quote with Autoslash for 274 GBP for the same dates, vehicle size, etc with the only difference being Autoslash "guarantees" automatic transmission while Costco does not. I also checked all the boxes for memberships and credit cards on Autoslash, but the difference is still 90 GBP. If that's simply the cost/difference to secure an automatic transmission vehicle, then so be it and I'll likely have to pay to get it. I was merely cross referencing the two quotes and trying to understand why.

Thanks for the data point and info on your vehicle.
