Need a cool car under £4k

My Subaru WRX is dying and I’m having to sell on eBay as the rust is too much. I’ll have around £4k to buy a car, last time I bought a car was 8 years ago, and now you can’t get F’’k all for that it seems. I need 4 doors, petrol, reliable, and something cool… this is looking like an impossibility. Am I over looking something?
