I like Darrell's "Fun-per-Dollar" ratio idea. Since I consider it fun to show my cars and have people look at them, I'd suggest a way to calculate the "FPD" ratio for each D at the next Delorean show might be: (Average number of spectators standing around a given car / Owner's total investment in the car) Hmmm. Interesting. Steve VIN 2650 ("Project Delorean") www.angelfire.com/md2/projectdelorean
