I have a 63 reg C180. Its been driving perfectly okay for almost a year now, but for some reason I can smell gas from the outside (but not inside) of the car before I even start the car. The smell usually comes through the left hand side of the bonnet, but I couldn't see any oil leakage under the bonnet nor any oil stain on my driveway. What kind of problem is that? Should I get someone to look inspect it properly?
Many thanks!
