A great idea and I celebrate it! However, it has come to my attention that backing the rear seat, while good and groovy, will be periodically ruined by removal as getting to the bevel box to drain and change the oil is now recommended for every oil change! It is SO much easier to have access back there this way!
Reason I mention this is that Morgan has now changed their recommended bevel box change intervals to the same as the engine oil. It is a good idea.
