You may be looking for a new car cover for your pride and joy and appart from avoiding the cheap and cheerful covers that may do more harm than good, what else should you consider?
If buying a cover from an overseas supplier, many companies and manufacturers have policies where if your covers becomes faulty, you have to return it for inspection or repair. This can be very expensive if you have to send a 4 kilo package to the states for example costing you £40 upwards. This also applies quite often if you buy a US manufactured cover from a UK supplier. If in doubt ASK!
