FAQs
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. We’ll be happy to continue taking care of your car’s maintenance.
The V5C logbook is sent to you by the DVLA after purchase. It usually takes a few weeks; typically you can expect it within up to 6-12 weeks by mail.
We’ll provide the service history documents to you when you get the car. If it’s digital, we’ll give you a printout or email, and if the car has a service booklet, that will be in the car’s documents pack. Essentially, at the point of handover (collection or delivery), we’ll hand you any service records or tell you how to access them. So you’ll have the history in hand right away.
It depends on the car’s recommended schedule. Typically, cars should be serviced once a year or roughly every 10,000-12,000 miles (whichever comes first). If we’ve just serviced the car before delivery, your next service would likely be due in about a year from that service date. We’ll let you know the last service date and any upcoming due dates when you purchase the car.
If the car just had an MOT done as part of our prep, then your next MOT is due one year from that date. If it’s a nearly-new car under 3 years old that hasn’t needed an MOT yet, then its first MOT will be due when it turns 3 years old. We’ll let you know the MOT status and date when you buy the car, so you’ll know when to plan for the next one.
