I have been grapplying with the idea for a year now. I have an nice example of an 86TR red/blk that drives like no other. In Ontario I have noticed a many 512TRs around and are stunning, but the price difference is making me wonder. I have thought and strongly considered with the difference to add another horse to the stable, this time a 4seater to have two in the garage. That was the original plan for the last 12 months. But......I saw the 512 live last week and im thinking maybe the heck with the 4 seater and the family drive, I want the 512. I would like to hear what others would do if given the options. 512TR? or a TR and 4 seater ? Would appreciate the feedback, including service cost ideas and the like. Thanks.
