£200 is more than enough mate, dont think you'll spend that much.
At the end of the day its down to you and everyone has their different opinions and requirements. You need two sets of s**t; The stuff to wash and dry your car properly, and the stuff to protect it.
I still think what I recommended is a good solid winter solution, one that will look good, provide long lasting protection and be economical. FK1000p is a tried and tested sealant and a favorite for winter and Tripple is a great All In One product which will leave a great finish and hide some swirls.
Heres what I'd recommend for washing, as its what I use. I prefer to use a Zymol Sponge but I go through about 4 a year and require a bit more care than a mitt IMO. No better or worse. See Clean Your Car
Coupled with the protection stage...
PS.
I believe that 90% of the paintwork damage is caused by drying towels, so look after them. Two bucket method during the wash stage will minimise swirls and wash marring, keeping the drying towels clean and storing them in a box when not using them is crucial IMO.
