The problem is that 'sod it and stick with the focus' is clearly the best overall option at your price point, unless you start finding some more cash to get a different motor that is [a] fuel efficient as reliable as the focus and [c] is more comfortable for your back. The other problem is that the difference in seating quality between a Focus on whatever else you can afford isn't particularly great unless you buy something really old and a more costly drive to maintain. . . . . I'm just saying no point in getting snarky with the others in the thread when we're pointing out the best option to you imho.

Just looking on eBay you buy all the Recaro seats pulled out of a used ST for around £200 and they should be a straight swap but I would pay your local garage to do them if I was you it’s probably more tricky than it sounds. Try and find an ST for sale somewhere to test the seats.
Cool, will have a look around
Im 6ft 5, drive a 9th Gen Honda Civic 1.8 petrol, easily gets me 47MPG if driven sensibly, seating positions nice and upright with plenty of adjustability, huge boot, magic seats and you can pick up a nice 2012 model for a reasonable amount per month.
Cheers,will see what's about then
