Keep Or Sell? 3RS/Spyder vs Cup

[Trackrat]

So, the inevitable slippery slope question has come forefront:

Dump the affectionately monikered "Piece of Crap" (3RS) and probably Spyder too and buy a Cup?

DE and TT track fun only for me. No real interest in racing. I don't think. The Cup would be a later model with sequential tranny.

1. Is it essentially a given that I must return both modded cars to stock in order to not take a complete and total financial bath upon selling? Or does a market exist for professionally and intelligently modded cars?

2. In a previous thread I proposed and supported a case for tracking a well-modded GT car for fun. Is there a remotely rational (I know, I know...) case to be made for DE and TT'ing a Cup for fun?

I don't have to sell either or both, but it seems pretty silly to let the collection of garage jewels grow even bigger by adding a Cup and keeping everything else.

The 3RS and Spyder are set up as any super-enthusiast would want and it pains me to even consider this but here it is...I know some of you have been here and can offer some feedback.
