Big A++ for Bensport Alfa from my recent dealings with them.
Small family run business, very friendly and knowledgeable.
Took my 156 to them because 4th gear was unselectable.
Did the job without removing the gearbox, opened it up and cleaned it out.
Fixed it a treat and the total cost came to less than £100 including the oil.
Nowhere else wanted to touch it without removing the box, including a couple of gearbox 'specialists', which would have cost in the region of £500.
Courtesy car was also included.
Will be taking it back next week for a regular service and at a later date for the rear discs and pads for which i was quoted an unbelieveably cheap £153 using genuine parts.
If you live anywhere in the area i would highly recommend giving these guys a shout before you take it to your local garage or dealership.
