I personally wouldn't buy any car online, the cinch & cazoo adverts on the telly say they do a 300 point inspection & recondion everything on the car,

as if.
1) how could anybody do a 300 point inspection even if their going down as far as nuts, bolts & screws which would be very unlikely so thats a load of BS.
2) why recondition everything & risk losing loads of money, not everything can be reconditioned. The truth is more than likely buy it cheap like ex rental, finance repossesion or ex mobility, replace only what is absolutely nessesary with cheap parts, slap a load of filler & paint over any damage & out the door.
They're also a huge rip off as If you watch the ads look closely & you'll see their list of cars in which they are asking over £15k for a second hand Fiesta, I wouldn't pay that for a new Fiesta let alone a second hand one, they truly are awful cars as my uncle has one & everything on my Panda which would have been about half the price when new is 100 times better quality than any Fiesta. Even when I brought mine pre reg I still looked over it & took it for a good test drive as I would with any car, nowadays I always check the MOT history & if it is full of major advisorys & fails as long as your arm I stay clear of them, it was seeing lots of car for sale like that & the price of used cars at the time which made my decision to buy new/pre reg which soon after I ended up with my black Panda Pop with 10 miles pre reg for just under £8k & the current value of Panda's online with simular spec, age, mileage & not as good condition as mine are only around £1,500 less than I paid for my car so it worked out to be a very good buy.
