I have chased up on alot of these vehicles and i have these points to make:
a) there are sh*tloads of auto soft tops around as they r not selling as well as manual hardtops.
b) 4doors are very scarce and alot of those adds for 4 door diesels are just adds, they don't actually have them in the country yet.
I have been trying to find a 4 door manual diesel in the country right now and the last one I could find was sold in QLD last week and they still have the advertisement up because they want to sell them on order.
this ticks me off because I keep having renewed hope for a 4 door manual diesel to be here and for sale and alas, they are just a add for a car that hasn't been built yet...
