Travel Stroller

I currently have a silver cross travel set that I got from my sister, however it doesn't particularly fold down very small. We are going on a holiday to Wales in August, and will need a stroller to get my LG around in, that will fold down small enough for us to get our luggage in the boot too! (We have a Nissan Qashqai). Does anyone have any recommendations for good travel strollers that fold down really small that won't break the bank please? (Hopefully below £100, but could stretch to up to £150 if it will last) Thank you 😊
