FAQs
Cars come with a manufacturer warranty when new, usually lasting a set number of years or miles. How much cover is left will depend on the car’s age, mileage and the manufacturer’s terms, so we can’t guarantee this for every vehicle. The best way to confirm the exact cover is to check directly with the manufacturer.
If you’d like extra cover, we have warranty products available at the time of purchase.
A lot of our vehicles do come with two keys, but we can only guarantee that each car has at least one. If the car has two keys, we’ll provide both.Because keys can occasionally be misplaced or damaged during transport or preparation, we can only confirm the exact number at the point of test drive. To secure your car for a test drive, simply find it on our website and book with a refundable deposit.
All electric cars use manufacturer-made batteries that are designed to last many years. Modern electric car batteries are carefully managed with cooling systems and safety margins, so they usually last for the lifetime of the car. We don’t provide battery health reports ourselves, so for the most up-to-date details on battery health or warranty cover, please check directly with the manufacturer.
You’ll need to bring your driving licence. If you’re part exchanging, please also bring your V5, service documents, and spare key. If you’re part exchanging and have a private plate, please refer to this FAQ about part exchanging with a private plate
Even if the car is in a zero road tax band, you still need to register it as taxed each year. The process is the same, but you won’t be charged anything. So you’ll need to go online or to the Post Office and 'tax' it (it will show a £0 fee). It’s important to do that so the car is officially recorded as taxed.
Our technicians are highly qualified and experienced. They are trained professionals who specialise in inspecting and preparing used cars to a high standard. Every car undergoes a rigorous inspection by our technicians, who have lots of experience in the motor trade. In short, you can trust that knowledgeable, certified mechanics have checked over and serviced your car before sale.
No, we don’t offer GAP insurance. You would need to arrange GAP insurance separately if you want it.
Yes. We we partner with HiQ to provide servicing, so you can absolutely book your car in with us for routine servicing. Just visit our Carsa Service website or call the service centre, and you can schedule a service appointment at a location that’s convenient for you.
