What is slightly daft is that some who go to lots of trouble speccing their beloved Mog end up not driving it hardly at all and then it ends up on Pistonheads as a very low mileage car , why I wonder when they went to all that trouble ?
point taken... but I doubt that will be me... drove an 1989 MX5 for over 10 years as an only car and never had an issue with it...
Some time ago there was a thread discussing the factory asking the dealers to carry stock in order to ensure people had test drives etc. They built a finance program to support this.
My guess is that some of the cars you mention are probably these carts being sold on the end of their demo period? The dealers do tend to spec them quite nicely.
As mentioned being able to spec the cars to your own personal taste is great but being able to get a nice spec the same day for instant gratification at a good price will make quite a few people jump I suspect.
