Steve Spent some time in a diablo. A boxer is like a fast or quick road car, a diablo is like getting launched from an aircraft carrier brutaly fast and it just keeps comming. Older lambos are grude compared to ferraris, think mercedes vs camaro. Each has a very different appeal. Personaly I woould go for a black(it blends the grates) 512tr over a diablo. although the last year or so diablo had a countach type front that was really cool. But then you have a fast pantera so maybee the extra go of a lambo is where you need to go.
I bought my 91 TR last January. 14,500 miles with a fresh 30k service for $64k. Hopefully with love and a clean garage it will hold the value for a year or two.
