If you are looking for garage to fix your car (as opposed to parking your car) then we have always found Sav at Clerkenwell Motors to be very good - it's just a small workshop but they are always happy to fit you in, the car comes back washed and if you live close enough there is a pick up service too. And the work always seems to be fairly priced and the car always works well after taking it there. But it's not the sort of place to go to if you want somewhere with a big plush reception and an authorised dealer's stamp for your log book!
