So three quotations for two year plan (1 major, 1 intermediate) obtained from my nearest dealerships......
*Reading: £870 inc VAT (half price MOT's, 10% parts discount, discounted labour, free brake fluid change).
*Guildford: £840 inc VAT (free valet).
*Twickenham: £756 inc VAT (no additional benefits).
Currently still in negotiations but Twickenham have my business unless the others can offer a more competitive deal, also felt Twickenham wanted my business and were knowledgeable about the ISF.
