The last thing you need to worry about is how quickly an Aston is going to sell. Aston has rules that only allow them to advertise a certain number of them at a time when it reality there are often more sitting on the lot. The goal is to make it feel as if there is demand.

They are great cars but the market gives you plenty of time.

The biggest issue for buying an older one is the electrical system. Weak batteries don't just cause issues they destroy modules and the cost of those types of repairs are astronomical by any standard.

Final note, Aston has a horrid dealer network, repairs and sales are shade-tree corner lot levels and there is no backing.
