Buy it if you want. This is not bad in our unit. After several projects, they are still the same as new ones. It's not a big problem, a small problem, a phone call, and someone will appear to solve it soon, which is more timely. The purchase process I found is as follows: understanding relevant information, determining the intended vehicle type-dealer consultation, determining the vehicle dealer-salesperson introduction, test drive-determining the purchase vehicle type and payment method-loan: providing loan related information-credit evaluation, loan approval-vehicle ordering-payment signing contract-purchasing insurance, paying vehicle surcharge, vehicle and vessel use tax-vehicle inspection. I hope it helps you!
