I have used Herts Autogas for a number of years now. They not only do LPG conversions (their…read moreoriginal main business, I think) but also service air-con systems and do general mechanical work on diesel, petrol and (no doubt) hybrid vehicles. I must admit that I mainly started using them because they were near enough for me to walk to, but now I would not get my car serviced or repaired anywhere else. Richard runs a very professional team. My car always comes back working fine. They have all the latest diagnostic equipment that allows them to clear error codes and generally do a more thorough job than the main dealers. On the odd occasion when a very specialist tool is required they are able to use their contacts to sort out the problem without requiring me to have to bother going to the main dealer myself. They are hidden away on the Nup End industrial estate, map as above. I had second thoughts about writing this review as I don't really want them to get so busy that I have to wait for a slot but I thought that in the interest of the Knebworth economy I'd write this.

The service and knowledge of the guys who work in there is far, far superior to somewhere like Halfords. They often do stunningly good deals on radios/cd players for your car, and they fit the things free of charge if you ask them. Most of the stuff in there is priced competitively with places like Halfords, even though they're just an independent.

Superb in every way; best advice, support and great price…read more I live in Cockfosters, about 6 months ago, I discovered my side mirror damaged. Without hesitation I drove straight to Halfords in Friern Barnet to purchase a replacement. Luckily enough the store doesn't stock my car mirror but they can order one for me at £14.99 (fitting not included in the price). On my way back I drove through East Barnet Village and noticed Falcon Motor Accessories store; I stopped by, I was served a gentleman who was incredibly helpful; he really went the extra miles to help me. He came out of store to see my car and recommend a replacement mirror (priced under £5). That is not all; he returns to my car and help me to remove the damaged mirror and fit the replacement at no extra cost. I feel guilt that I am only writing this feedback now. From now on Falcon would be my first point of call for any motoring assistance.
