I love the comments here showing a lot of people have had the privilege of not buying at the bottom of the market. (I bought all my cars like this either old or my current one as is from a dealer needing to shift a high mileage trade in)
Take someone to look at the car who knows what they are doing, if the seller doesn’t want you to look under it or drive it first walk away.
Look at a few cars before deciding.
Don’t buy anything without it’s paperwork is in check and get a HPI before making a offer on a car you want.
Anything wrong on the HPI don’t buy.
Check the car has had regular oil changes and checking the MOT history on gov.uk will show you if the owner has kept it in a good condition.
Enjoy your bargain car, if you wish to pay cash your going to have to make daily ATM trips for a few days.
Bank transfer is better for private sales but don’t pay until you have them there about to give you the keys and the V5C new keeper slip.
Everything’s your risk but the scare comments here are just showing how snobby some people are.
