http://www.morgan-motor.co.uk/sales/used...p;submit=SearchThe MMC link is +8 specific but includes the newer Aero chassis ones.
The C@C link is selected for all Morgans of various ages - condition and mileage is everything as with all Morgans as I'm sure you know. £26,000 would be a good starting point.
If you would like specific information on a particular model pm me.
I have owned two and they are a great car if in good order - my current one is a 1999 3.9Ltr with 21,000mls at purchase with every extra imaginable and excellent condition at a cost £29,950 end July 2014. They are very addictive I have put another 5,000 miles on her since August this year.
Good luck.
