dealer told me I would need a detachable towbar because it has parking
sensors and at £240 + fitting I thought he was having me over, standard
towbar is only £120 + fitting.
Then I saw a C8, with parking sensors, with a normal towbar and bumper
protector plate fitted.
I got a standard Towsure towbar off ebay for £45 and fit it myself and
have had no problems with sensor false readings...
