I always used to think that my car, whatever model it was, drove more sweetly just after I had spent the day meticulously cleaning it!
I think it was all in the mind, which,of course, it was. One would naturally expect a car to perform much better after a service and whether it is the mind playing tricks or actually the service having "sorted" any issues, who really knows?
