Help with whether I keep my car or not.

So, I currently am 24. I have a secure job, 0 debt. I have saved 20k for a house deposit and it’s sat in an isa until the time comes, which is probably next year at some point- I will add more to this roughly 5k more. I have a car, that I HATE. It’s very economical, I do all the maintenance and work on the car. It’s becoming a high mileage car at roughly 90k. But, it’s cost me probably around £300 in maintenance in a year, £30 a year tax, and £300 a year insurance. I am a bit of a car enthusiast, and I really want a new car. Something that is fun to drive. The issue- I am so financially free, I can’t bring myself to get in debt again. So I would trade my car in, find some money and probably put a 8-9k deposit down on the new car, and then essentially put the remaining 8k on finance, over 60 months and aggressively pay it off by 1k a month for the next few months until it became around £50 a month, then chip away at it over the next 1 year ( there’s no charge for over payments from lender). However, I am pulled two ways- the car or the financial freedom. The problem is, I don’t really even go on holidays or anything because I don’t have time currently with my job. Further to this, I only have 1 holiday next year, and then the house to buy so realistically I won’t be able to go on more holidays or have the opportunity to buy the new car. What do you guys think?
