| KH (UK) | June 2008 | "Hello, I wanted to let you know that the gearbox you re-built for me is great. I have recommened you to my brother in law who also has a mini turbo and is looking for the same gearbox. Thank you ever so much. PS. straight cut gears sounds amazing." | |

The first advantage of dealing with Guessworks is the easy ordering through the website and clear information about what to order. Secondly, John is easy to get hold of for an update on your order and will do everything possible to help. Thirdly, Guessworks takes all the hassle out of the process by organising delivery and collection of your old gearbox. Lastly, John charges very reasonable prices for the service he provides." |
