Should I Sell The CLS6?

Alright, I got an opportunity here to pick up a clean white '06 TL 6MT with very low mileage for a good deal from a family friend.

I've always liked the TL.. it's newer, nicer looking, more practical, and a lot easier to mod. But then it's back to another bone stock car.

I got a lot of money dumped into the CL and I still love her to death (love-hate relationship, but still more love). I also got a lot of mods sitting around ready to go on, such as the TL lip kit, RL BBK, etc.

Here's where I gotta make a decision, I either gotta sell the CL now before I dump another 2-3k on her this summer, or keep it. The way I see it, if I install the RL BBK and mould the TL lip kit on, there's no way I can sell the CL after (too much $$$ invested).

I love the CLS6, I look forward to getting in the driver's seat every time. Mines is at 210,000km (~130,000miles), with new clutch, timing belt and some mods (comptech exhaust, aem intake, ur pulley, tein coilovers, ingalls camber kits, rsx wheel, pioneer double-din, etc.).

I dunno, I need some advice from my fellow A'Ziners, what would you guys do? I figure I can get like 5-6k for the CL tops.
