AUTOSPARX based in near the MEDWAY Tunnel. Though they also now have a superb mobile fitting service.
I have always had my cars done with them. Great guys, dont mind stupid questions, fit a lot of different makes and are fully qualified and certified.
Back about five to fifteen years ago most of the feature cars in FAST CAR or dare I say it "LAX FLOWER" that were based in the south and south east of the UK had their their alarms and other bits done by them.
