MJ INTERIORS are prob the best
or try Jamie shaw at Carisma
these are the 2 best places to go in the UK by most peoples un biased opinions
dont know the number for Carisma
but MJ can be had on 01274 533370 although he is on holiday till the weekend i think
retrims (for front and rear seats only) start at around the 850 mark... he did my recaros and did a awesome job, and he isn a really top geezer too who is well into the scene
i know having them done in fabric wont be much less as its still the same amount of work that has to be done
