Thanks for the responses, you are right, I shouldn't discount private sales, but I do feel slightly nervous about it due to my knowledge of cars and zeds is pretty small. I will keep an eye out though.
With regards to insurance, the best quote I have so far is £1,350 (£500 excess) which is from Swiftcover. Annoyingly, it is my postcode which is making the difference and keeping the car on the road overnight. Was quoted £940 for my parents address in surrey (on a driveway). Just can't justify over £1k for insurance and (thankfully) I haven't lived at my parents address for 8 years! I will continue trying the non-comparison website insurers and see if I can get anything better.
