Deal should be the same if paying cash.
Pros and cons for the cash vs. finance discussion. Personally I like to see cash in my account as you never know when your going to need it and if you can afford the finance then why not.
On another note I was in the same boat recently for a £25k used car. Finance was pretty poor from the dealer but Zopa give personal loans for 2.9%. Applied on Tuesday, in my account by Friday and didn’t have to speak to a human being...bliss. Was almost £100pcm cheaper than the finance the dealer offered me too.
