I just spend £258 inc VAT for the service on my Mito, and had to cough up an additional £11.83 in import/handling charges for a soundtrack CD of Blade Runner 2049 which cost £25 already, and which after I'd placed my order then got a normal cheaper release...
You shoild apply LMS/LNER/SR servicing schedules not GWR. Run it till it won't run no more, bodge it and run it some more and then finally replace everything, new frames, new suspension new taper boiler. None of this regular servicing Swindon style malarky
