Nice car, good price (if somewhat negotiable) and it will sell.
But.... The wrong time of year, which you can do nothing about.
Drop considerably now for a quick sale or hold your horses and wait for the right buyer.
My 2ps worth
I would agree with Boshly on this and as mine was on order and delivery was getting nearer it was the only reason I decided to drop the price and it went quickly.
Have you tried Miscellany? I've noticed we don't seem the have many aeros for sale at the minute. It might also be worth seeing where the buyer of Matts Series 1 came from?
