Welcome to the Armstrong Siddeley Owners Club

Centenary2019 marks the centenary of Armstrong Siddeley car production.

Celebration events will be held throughout the year, with the highlight being the largest gathering of Armstrong Siddeley cars for decades in Coventry on July 14th. We are hoping to attract over 100 AS vehicles to display at the Memorial Park in the city and everyone is welcome. If you have an Armstrong Siddeley car, whether you are a member or not, please bring it along in July to make the celebration one of the biggest in our history.

Car Of The Month

1939 16hp Coach Saloon

16hp Coach

KMP700 is finished in Denmark blue with blue leather interior. This particular car is from the ZC batch and is one of the last to be manufactured prior to the outbreak of WW2.

Purchased by its current owner in November 2018, she was previously owned by his father from 1983 to 1999. During that time, many happy memories were made taking her to local rallies, ASOC club events, national weekends and the Isle of Wight rallies and it was these reasons along with the love of the marque itself that she had to come back into the family.

Having had two owners in the interim, she has been used, enjoyed and loved. One of her former custodians enjoyed many overseas events with the club and has ventured to France and Switzerland amongst other places. Like us however, the passing of time can be less kind and in certain areas KMP700 now needs a little attention to get her back to where she once was.

With the help of his father, work is already underway on replacing some weak woodwork on the boot frame and in March she will be attending the Practical Classics Restoration Show at the NEC where more repairs and maintenance will be carried out. Looking towards the rest of the centenary year (as well as her 80th birthday) she will be attending the EAST event, the marques' 100th celebrations as well as many local rallies too. Further into the future will see some bodywork and leather repairs.
