Aptera is a new car manufacturer I doubt they want to be in the used car business or in the car financing business. My advice is to make your Aptera purchase easy for you and them. Sell your vehicle and line up your financing ahead of time. Make sure your finance company is very clear about what vehicle you are buying. Arrange for insurance for your Aptera ahead of time also.
Trade ins is a dealer function where they can resell or auction off the trade in vehicle. Aptera will not have a dealer network with its accompanying high overhead expense. This is a reason Aptera can keep their prices lower. With the shortage of used car inventory you can sell it yourself or there are auto networks that will buy your vehicle without you having to purchase one from them. The short straw in either case is you need a clean title before the sale which means you need to pay the vehicle off before selling it.
@Robert Keith Harrigan I agree but Aptera has said that financing will eventually be available so – considering their production model – I’d guess they might contract-out financing to a third-party firm. The same might happen with trade-ins. Leasing could also be handled by a third party…
Aptera will not do trade-ins. As a manufacturer, they are not interested in getting into the used vehicle market. In the current market, selling vehicles is quite easy. You can likely just sell your previous vehicle to an existing dealer very easily.
